In such case, it is recommended to check Colibrick Setup in the System Configuration window. Synchronize Start with Digital Input should only be enabled when one of Colibrick's digital inputs is configured as Exr. Start Dig. Input:. Furthermore, Synchronize Start with Digital Input and Exr. Start Dig. Input: must be set to the same Digital Input.
This change was made because the wrong setting led to random issues with analysis starts in previous versions. 
Synchronize Start with Digital Input enables a faster and more accurate synchronization of channels with the start signal. The start of the analysis is defined by a marker in data points rather than by detecting the change in Digital Input. The difference is in the order of hundreds of milliseconds, which means that it is important only for very short analysis. When measuring multi-detector chromatograms it will minimize the time shift between detector signals and thus improve the detection of peaks.

Bar code scanner support is implemented within a few autosampler control modules (Spark Integrity, HTA HT4000, …). The read bar code will be available as the %f variable for use in SampleID, Sample, or Filename fields. Hand-held scanners (emulating keyboard) could be used to fill in the values in the sequence table – the terminating character should be set to Enter, and the setting in the User Options dialog - General tab - Sequence Table - On Enter section should be set to Move Down option to move the focus to the next row after the Bar code value is read. For versions before 9.0, the option to set the terminating character to Down Arrow in the scanner will be advantageous; otherwise, moving to the next row using the mouse/keyboard is necessary.

It is not possible to install Clarity on Windows 10 LTSC releases, where .NET Framework version 4.8 or newer cannot be installed (this should apply to Windows 10 Enterprise LTSC 2015). Clarity installation requires .NET Framework version 4.8, introduced as part of Windows updates in 2019 (Windows build 1903). Importantly, DataApex cannot guarantee complete Clarity functionality in LTSC Windows releases, as they are not among supported OS (only OS with the latest updates is fully supported) and are not properly tested with Clarity. All Software and Hardware requirements are listed here. You can test whether it is possible to install Clarity to the system by downloading and installing Clarity Demo.

Serial Number (S/N) and User Code (U/C) are two essential identifiers for our software. The S/N is a 7- or 8-digit number representing the station's serial number. It is saved in the HW key and is permanent, meaning it doesn't change with the Clarity configuration change. Whenever you ask for technical support at support@dataapex.com, you will have to provide your S/N. On the other hand, U/C is a 16- or 17-digit code that defines the configuration and version of the chromatography software. It is formed from letters and numbers and unlocks the specific Clarity configuration in a specific HW key. You will need to enter the U/C during the installation process, and when the configuration changes, you must set the new U/C (usually received via email) in the Clarity main window - Help - User Code... dialog. S/N and U/C can be found on the packing list, and installation media. You can also read the S/N and U/C from within the software (main window – menu Help/About).

Most problems with Colibrick are related to the USB power supply. So if USB hub is used, we recommend using a hub with an external power source. It's important to note that Colibrick is sensitive to communication delays. These delays can be caused by issues with the computer's hardware or software, such as processor overload, low RAM memory or running processes blocking the processor or communication lines. If there is no communication for more than 10 seconds, an error message will be displayed, such as "No data from Acquisition" or "No data received for...". This will cause the acquisition to stop and the running sequence to be interrupted. If the problem is temporary, resending the method may solve the problem. Otherwise, try disconnecting and reconnecting the USB hub. To check for issues, use the Task Manager to inspect the processor load and processes consuming a large amount of CPU time or memory. Programs that can cause issues include incorrectly set anti-virus programs that continuously check file types used by Clarity during data acquisition. To avoid this, disable the *.raw, *.prm, *.audit, and *.tmp file types for scans. Other programs that monitor files on exchangeable media, such as programs for organizing and presenting pictures, music or video may also interrupt the acquisition. It's also important to note that any actions started during the acquisition, such as printing to a slow USB or network printer, large file transfers over network or USB, connecting or disconnecting USB devices, computer entering sleep mode can cause the acquisition to be interrupted. Finally, it's worth noting that the communication problem with Colibrick can be avoided by connecting the USB hub to the USB C connector on the PC.

There may be multiple different reasons. Please check the detailed status in the Instrument window and Device Monitor. - Waiting for Injection - indicates parameters for injection were sent to the sampler, but the start signal has not yet been received.
Suppose the sampler is not working on the injection. In that case, it may indicate wrong synchronization settings in the System Configuration or that the start signal was not received or ignored for some reason. - Waiting for Hardware to be Ready to Run - indicates some of the devices configured on the instrument do not report Ready state.
Check the status reported by individual devices in the Device Monitor. - Sequence Paused - indicates the sequence was paused.
An automatic pause may happen if an invalid value is entered during the editing of the running sequence to prevent locking a line with an invalid value. After correcting the value, the sequence must be manually resumed.

This usually happens when upgrading Clarity from an earlier version. The IQ program checks all registered files and, if they are no longer used in the new version, will cause the check to fail. However, the station will usually function correctly. To get Passed for IQ results, it is necessary to: - Remove the previous Clarity installation using the Uninstall Clarity command from the Windows Start menu - All Programs - Clarity program group.
- In case you can still see some *.dll files in C:\Clarity\Bin (since 7.0), delete them manually.
- Install Clarity again.
The Uninstall Clarity command will remove the program files only, leaving the configuration and data intact. In Clarity versions prior to 7.0, *.dll files were present in the C:\Clarity root directory.

The "No Data received for 10 sec" or "No data from Acquisition..." messages mean what they say, no data were received from a detector or A/D converter (Colibrick, etc.) for a certain time. It may be caused by several cases: - In most cases, there is some problem on the computer - processor overload, interference on the USB bus, time-consuming net search, or backup operations blocking the communication for some time. The error invoked will stop an acquisition or interrupt the sequence.
Suspected programs are incorrectly set antivirus (continuous checking of file types used by Clarity during data acquisition - raw, prm, audit, tmp should be avoided), programs monitoring files on exchangeable media (i.e. programs for organizing and presenting pictures, music, or video, including some CD/DVD burning programs). One such persisting problem was reportedly solved by removing the Roxio Burning software.
This will occur more frequently on slow computers, the triggering action may be processor overload or some programs blocking the communication for an extended period.
- In some cases, Windows may suspend the power of the USB HUB in the computer and this unexceptionally causes a loss of connection to connected HW (e.g., Colibrick). Try to check the Device Manager dialog - Universal Serial Bus controllers. Display the Generic USB HUB Properties dialog - Power Management tab. Set Disabled for option Allow the computer to turn off this device to safe power. In case the problem is temporary, sending the method again may solve the problem. If not, disconnect and reconnect the USB HUB.
The above-mentioned problem with communication was not observed when the USB hub is connected to the USB C connector on the PC.

Clarity stores the IP address of the device detected during autodetection in the configuration and if it changes, it is unable to communicate with the device. Some devices use IP adress assigned by DHCP server in default settings.
If the system is connected directly to the computer or via a switch, it is necessary to set static IP addresses in the devices and in the LAN card in the computer (preferred solution). Refer to the device manual or contact device manufacturer/supplier for how to change the device setting to a static IP address.
If the system is connected directly to the computer via router, it is possible to use DHCP IP address assignment, but you must ensure that the assigned IP addresses do not change. The same applies for connections via an internal network, where the cooperation of the network administrator is required to set the IP address.

During acquisition, data are stored in the temporary directory (...\TMP\ $ch1run.raw file ). The data are stored from memory to disk in approximately 1 min intervals. In case the Clarity crashes/freezes during a run, the up to that moment acquired data could be recovered using the Data Recovery ... command from the Single Analysis window. Note the chromatogram will be created according to the method and parameters specified in the Single analysis (file name and processing parameters), which may be different from the ones used in the Sequence.  
During the freeze, it will depend if the thread collecting and storing the data to disk will be still active, with a crash, the data to the last minute before the crash could usually be recovered. In case the computer freezes often, it will be advisable to investigate the cause and try to find a remedy – please do not hesitate to send us the respective diagnostic files. A Memory dump may be helpful for such situation.

The error message pops up after the start of Clarity.   This problem is caused by the wrong configuration file saved in Clarity\cfg. The most common reason is that the computer was shut down while Clarity was running. Normally, Clarity saves the clarity.cfg file when exiting, but when the computer is shut down while doing this, the clarity.cfg file may be corrupted and cannot be used in Clarity next time it is opened. The corruption of the clarity.cfg file may happen in numerous ways. Here are the two most common situations: - When the computer is switched off while the Clarity is running, e.g., while experiencing some fluctuations in the power system.
- When the computer is switched to the sleep mode, while Clarity is open, but not running (e.g. during lunchtime). While the analysis in Clarity is running, Clarity blocks switching to the Sleep mode, but without it, it can't do so. In sleep mode, the computer loses the communication between Clarity and the A/D converter and/or hardware key, which may result in destroying the configuration.
All data, such as methods, sequences, data files, calibrations, etc. are saved on demand and are not corrupted when a similar situation arises. The clarity.cfg file holds the information of the Directories and the System Configuration settings, that are lost, so they must be set manually once more. To repair the damage, follow this process: - Open the System Configuration dialog and configure your system manually (eg. add detectors, LCs, GCs, valves and so on to the configuration), fill in their settings and distribute them to particular instruments.
- Close the System Configuration dialog by clicking OK.
- If you had the Directories dialog set before, use the System - Directories command from the Clarity window to set it once more. Then, close the dialog.
- Open the Instrument. Load the desired project to the Instrument; Default clarity.cfg file has the Work1 directory set as the project directory, you have, most probably, created your own project before the shutdown. Use the File - Project command, select the appropriate project from the list and press the Open button.
Note: You might get the information similar to "the current method was prepared on a different configuration. Some parameters will be used in default format" if you opened and then saved the method after the clarity.cfg file was corrupted, there might be necessary to check/set some parameters, mainly on the Method Setup - Acquisition and Method Setup - Measurement tabs. - Exit the station. The clarity.cfg file was now saved with the correct settings of the configuration.
- You can back up this configuration to some other directory to prevent the manual settings if the problem occurs again.
The station should now be in the configuration as before the failure. To prevent this from happening in the future if the reason was the sleep mode follow the procedure: - In Windows 10 and 11 invoke Settings - System - Power & Sleep - Additional power settings - Choose when to turn off the display - Change advanced power settings and set Sleep after item and Hibernate after to "Never". Apply changes and use OK to exit this dialog.
- In Windows 7, 8.1 go to Control Panel - Hardware and Sound - Power Options - Edit Plan Settings to change the settings.
Corruption should be prevented in the future. Of course, if it was caused by another reason, such as instabilities in the power network, only a good stabilized backup power source and backing up your configuration may help.

Installation- Installation to program files: In Windows 7, the folder Program files is protected, however, Clarity needs user access to the data and system files. It is not recommended to install Clarity there.
User privileges settings:- Clarity users must have read/write access to the Clarity system and data files. The default C:\Clarty (C:\ClarityLite) directory inherits the Read Only status from C:\ on administered systems. It is recommended to Install Clarity for the User that will use Clarity under the "As Administrator" option. If not possible, contact your local administrator to change the settings.
Antivirus programs:Antivirus programs usually do not interfere with Clarity functionality. But two areas may pose problems for the correct functioning of Clarity: - Antivirus is causing processor overload in certain situations, which may leave insufficient memory resources for Clarity.
- Antivirus continuously monitors files frequently updated by Clarity (.raw, .audit, etc.), which may be unjustifiably marked as a threat to the PC.
Windows Updates:Automatic Windows updates are in the default settings that force the unattended computer to restart regardless of running programs - only a warning message will appear. Please note that the first two options (Automatic updates or Download updates) may result in a forced computer restart. We recommend installing and operating Clarity on a PC with updated OS, only the forced restarts pose a potential problem to Clarity. In Windows 10 and 11, it is not possible to forbid the updates; just pause updates for a short period of time and install them manually to avoid forced restarts. Go to Settings - Windows Update - Advanced Options - Pause Updates In Windows 7, 8.1 go to Control Panel - System and Security - Windows Update- Change settings.
Choose one of the options for automatic updates: - Never check for updates.
- Check for updates, but let me choose whether to download or install them.
Ask your local administrator to choose one of the options described above on administered systems. Control Modules and ToolsUser Account Control (UAC) needs to be disabled during the installation of some control modules (CTC PAL, Shimadzu LC systems)To install the CTC PAL autosampler or Shimadzu LC-10/20 system it is necessary to disable the UAC (User Account Control) during installation, otherwise, it will be unsuccessful. Similar problems were reported for the installation of the Agilent 1100 system, again the UAC disabling helped.

Clarity is a 32-bit process, which means it can use the max of 2GB RAM, but if you use more than one demanding instrument, it can still be beneficial to have 8 GB RAM, so the PC has enough RAM left for OS and other apps. In Clarity 9.1, we reduced the risk of out-of-memory events when using Agilent ICF due to improved memory usage. Operations with modules utilizing Agilent ICF are moved to a separate process so it can use another 2GB RAM. So we recommend upgrading to the latest version. If you still get the "Out Of Memory" error, e.g., when opening a chromatogram in the Chromatogram window, it may be caused by using a particular method, which has been saved over and over again due to some modifications. Since version 8.3, every saving of such a method results in creating another method version (the number of versions is displayed at the top of the Method Setup dialog behind the method name as "- #number"). These versions increase the Method file size; memory can be depleted when such a large method is used, forcing the software to misbehave. As a remedy: - Try to save the method using the command Save As under a new name. This will save your method without previous versions, decreasing the file size.
- Do not use "Open chromatograms in Overlay" when running a Sequence.
- Do not open resulting chromatograms when Sequence is running (Disable the checkbox in the Open column).

When Clarity (Lite) is started, an error message stating "Missing HW key" may appear. This issue arises when the required hardware key is not detected by the system. If you encounter any problems, the first step is to check the USB port the key is plugged into. Try moving the HW key into a different USB port on the PC or another PC. Most issues are related to the USB port's energy-saving settings in Windows or a faulty USB port.
 The Rockey USB ND does not require any separate driver installation; once plugged into a USB port, all necessary drivers are automatically installed. For problems encountered in the case of older keys, see the section below. Make sure that the LED diode in the key is steadily lit. If it is blinking or it is not lit at all, the hardware key may be faulty, and you will need to send it to us for inspection. Please contact us at sales@dataapex.com in such case. Old HW key typesThe older HW key types require drivers to be installed prior to their use. The Rockey USB/LPT and Sentinel USB/LPT HW keys might not be functional due to installation of a wrong driver. This situation occurs in the case this HW key was connected to the PC before the installation of the correct driver by Clarity. This can be solved by manually uninstalling the wrong driver, restarting the PC, and installing the correct one. To do so, the installer of the drivers can be found in the Clarity\BIN\HW_DRIVERS\ subfolder. 
Sentinel HW keys cannot be used with the current Clarity release.

If you add a User Column to both the Summary and Result Table containing the same formula, often you cannot get the same results. You cannot use the First, Last, etc. functions from Special Values in the Summary Table. For example, "[Reten. Time]first/[Reten. Time]" will not work here. But you can use figures working with the compound itself, for example "[End Time]-[Start Time]".

Yes, it can. However, the philosophy of use is slightly different. The peak areas of a selected group of peaks are summed, and the group can be named and calibrated as a single compound. Please refer to the corresponding parts of the Reference and User Guides. Especially in the calculation of the Result table Total line and Amount % column, there are potential problems, if the calculation procedure is not understood correctly.

If you experience a long delay when downloading the Clarity installer from www.dataapex.com and the download process seems to hang when it's almost complete, it's possible that your anti-virus software is scanning your web communication and downloads for viruses, which can cause the delay. The delay duration depends on the file size and anti-virus SW used.

Multiposition valves are frequently used as a simple fraction collector for preparative purposes. Knauer provides dedicated control modules for multiposition valve-based fraction collectors; however, they are available only in the ClarityChrom OEM version. To use valves for this purpose in Clarity, combining a two-position (three-way) valve to perform the Collect/Waste function and a multiposition valve to perform the Next vial function is usually necessary. Clarity Valve control modules also support the needed Next position command. The fraction collector can be easily created using the General Purpose Fraction Collector module (requires A24 LC control module) and one of the controlled selection valves (Upchurch, Vici-Valco, or Rheodyne MX II series), the fraction collector can be easily created.

If your PC and chromatograph are connected directly via LAN and autodetect is not possible, continue with the following procedure: - You need a cross-over ethernet cable (a straight-through cable is not recommended).
- Open Windows Settings - Network & Internet - Ethernet tab - Change adapter options - right mouse click on the Local Area Connection and choose Properties.
- In the Local Area Connection Properties, choose Internet Protocol Version 4 and click the Properties button.
- Check the radio button in the Internet Protocol Version 4 (TCP/IPv4) Properties window. Use the following IP address.
- Fill in the IP address.
- The first three positions define the network and must be the same as in the device's IP address.
- The last position defines the device and must be unique within the network, so do not use one of the connected instruments. Eventually, other Ethernet boards within the computer must not share the same network.
- The subnet mask needs to be 255.255.255.0

The peak detection algorithm used in FC-GP can be explained using the figure below. The red color is the signal, and the blue color is the derivative of the signal (basically a slope at that moment). The axis on the left is shown in the units of the derivative. For illustration, there are two green vertical lines at 2 and -2 (let us assume the slope has a start value of 2 and an end value of 2).  The first peak is collected when the derivative raises over limit 2 (first upward black line). The peak is collected through the peak apex (even before the derivative falls below 2) and is still collected when the derivative falls below -2. Then, it rises, and the peak-end is triggered when the derivative increases from some -4 above -2 (which is the negative of the end limit). If the derivative on the peak-end never falls below -2, the fraction will never end (until the end of the collection interval).

It is possible to schedule a task that will run Clarity with defined parameters automatically starting a sequence. Proceed as follows: Prepare a batch file (clarity.bat) to perform the required tasks using the command line parameters
The batch should contain the following line (example): - start C:\Clarity_Demo_304\Bin\Clarity.exe i=2 u="Administrator" psw="" seq=C:\Clarity_Demo_304\FC\FC3.seq run_seq=2
Explanations: - start C:\Clarity.exe will start the Clarity in the specified directory
- i=2 will open the desired instrument (2)
- u="Administrator" psw="" will open it as a specified user with a specified password (essential, otherwise it stay waiting for this input)
- seq=C:\Clarity_Demo_304\FC\FC3.seq specifies the sequence to run
- run_seq=2 starts the sequence on instrument 2
- Prepare the sequence to be started
The sequence can contain just one line with the start-up method, or some standards/samples can be defined in the following rows. In the start-up method, define to switch the lamp on and flush the system as required to equilibrate. - Use the Task Scheduler
Set the clarity.bat to be started at a defined time and date. Open the "Task Scheduler" Windows app. Use the advanced properties of the task to fine-tune the scheduling.
Set the task to start when you are logged on only, and when leaving the PC, do not log yourself off. Remember, Windows Update must not run there. It may log you out and restart the PC.
The path in the batch file can differ according to Clarity version you use (version up to 6.2 - start C:\Clarity_Demo_304\Clarity.exe i=2 u="Administrator" psw="" seq=C:\Clarity_Demo_304\FC\FC3.seq run_seq=2).

If it is required to print the audit trail of the method (*.met) file, it is necessary to perform this print directly from the Method Setup dialog, where the correct method is opened. Report style has to have the 'Method Audit Trail' option checked on the 'Audit & Signatures' tab in the Report Setup dialog. Even with these options checked, the audit trail won't be printed when printing from a different location (for example, from the Chromatogram window). This means it is not possible to print a chromatogram together with an audit trail of the method (*.met file) used for its acquisition in one Printing session.

The Clarity software has several system files that are important for storing various data related to its functioning. The list of the files with default paths: - C:\Clarity\Cfg\Clarity.cfg
This file stores hardware configuration information, along with information about the last user who logged in to a specific instrument, and custom instrument pictures used in the Main window. - C:\Clarity\Cfg\*.dsk
This file stores information about the last used project (*.prj) and individual user preferences such as windows configuration and layout, tables and graph preferences, user columns, and more. - C:\Clarity\DataFiles\Projects\*.prj
This file stores information about project subdirectories (the project directory has the same name as the project *.prj file) and the last used method, sequence, SST method, chromatograms and other files. - C:\Clarity\Cfg\Clarity.psw
This file stores the list of users and their access rights. - C:\Clarity\Cfg\Clarity.sno
This file stores the identification of the station.
It is recommended to back up these files to prevent data loss in case of an accident. Please note that up to version 6.2, the Cfg subfolder did not exist, and the files were present in the root folder.

Most chromatography systems use a proprietary data format (the main reason is the belief that it ensures data integrity for GLP-related requirements). To open and process such chromatograms in Clarity, they must be first exported from the original software into a suitable format. The most commonly used formats are AIA (.cdf files) or ASCII (.csv, *.txt, *.asc, and others). Clarity can import such files (only the chromatogram data, not the integration method or result tables) and process them using the current instrument method. Chemstation - The export is available with full menus active in the Data Analysis view (menu File, command Export file, AIA file....). Due to the way the Chemstation exports the files (they are always named signal01.cdf and stored in user-named folders; batch export is not supported), the processing is not very convenient and will be quite laborious for a large number of files.
- The export of DAD data is even more complicated, if not impossible (you will have to export each wavelength separately and combine them to the format that can be imported to Clarity).
EZ Chrom - The chromatograms can be exported during processing, in the Advanced Method Options, Export tab for option Chromatogram the AIA and ASCII formats can be selected.
- The ASCII *.asc file format is supported by Clarity both for chromatograms and 3D data. AIA files can be used as well.

The Clarity software license is fixed on the HW key. The software itself could be installed freely on different computers, but without the HW key, it will not start. To move Clarity to a new PC, follow these steps: - Install the software on a new computer (the latest version can be downloaded from our website, www.dataapex.com, section Downloads; you need to be registered and logged in). During the installation, ensure all necessary drivers and control modules are installed - some may not be included in the Typical installation.
- Connect the hardware (MultiCOM, A/D Converter, etc.) and the HW key.
- Enter the user code matching the HW key.
- To restore your settings, copy the system files (Clarity.cfg, Clarity.dsk, Clarity.psw) from the old computer to the Clarity\cfg folder on the new PC.
If you have Clarity Full version: - To restore the data, use the Archive/Restore command to copy the needed projects or the respective folders (including the Projects and Common).
If you have Clarity Lite: - To restore the data, copy the respective folders (including the Projects and Common).

In Clarity, up to 4 independent configurations can be set up - one on each available Instrument with an independent time-base. Up to 32 signals/channels can be acquired on one Instrument. The core software (p/n C50) includes only one Instrument. Please note there may also be specific limitations given by the controlled instrument (for example, only one Agilent 1100 system using HP-IB communication or only one Shimadzu LC-10/20 system may be controlled by the Clarity station) due to the communication protocol constraints.

If you have bought an extension or control module license, you will get a new user code for the latest SW version and have to use the version compatible with the user code (if you have it, there is no need for reinstalling). On top of that in the case of a new control module, reinstallation depends on how you installed Clarity originally (typical, full, or custom installation). If you miss any control module in the System Configuration window, you must reinstall Clarity.

The sample rate needs to be set to provide enough points to describe the peaks of interest adequately. It is recommended that at least 30 points be reached per the narrowest peak width. The default value for DataApex's A/D converters is 10 Hz. This is suitable for most HPLC and packed column GC applications. The capillary GC and CE applications may need higher sample rates. Accordingly, the Global Peak Width parameter must also be amended to match the sampling rate.

LAN communicationGeneral issuesFor LAN communication, one of the 1100/1200 modules must be equipped with a LAN communication card inserted in the MIO slot on the backside of the module (do not mistake it for the CAN connectors used for the internal system communication, using the same RJ45 connectors). The original board supported by Agilent is a G1369A LAN Interface described in Agilent G1369A LAN Interface User Manual (Agilent P/N G1369-90000). We don't support J4100A JetDirect card (alternative to HP JetDirect Print Servers 600N/400N/500X/300X) nor guarantee the functionality. Connecting single PC directly with 1100/1200 systemIn case you need to connect the PC directly with the 1100/1200 system using a LAN card, see chapter 3.3.4 Single PC & network connection in the Agilent 1100 manual. GPIB CommunicationCommunication using GP-IB card could not be establishedWhen the communication with the Agilent 1100/1200 system by the GP-IB card could not be established, even if all the parameters are set correctly and the Agilent IO Libraries report the module as connected on the used ID address, then it is necessary to check the Agilent IO Libraries. The Agilent IO Libraries must be closed (Use the Exit command) before the communication with Clarity can be established. During the installation of the Agilent IO Libraries, they are added to the programs to be started automatically at the system start. It is necessary to disable this function because they could not run simultaneously with Clarity. - In Windows XP, Vista and 7 - remove them from the Windows Start menu, Programs (All Programs), and Startup group.
- In Windows 8, 10 and 11 - start the Task Manager (display more details in the window) and locate the Start-up tab. Disable them.
After the communication was lost, it could not be reestablishedWhen using the GP-IB USB converter, it may be necessary to disconnect the converter from the PC to clear the communication buffers. As the USB can be powered even during a computer shutdown, the shutdown and restart may not help.

Most probably, yes, the list contains only directly controlled autosamplers. In other words, those where it is possible to set the position and injection method using a computer. Nevertheless, Clarity allows basic synchronization (allow injection and start data acquisition) with arbitrary autosamplers equipped with appropriate control output and input. For more information about AS connection, refer to Chapter 6 (Connecting Autosamplers) in the Getting Started manual.

There are a couple of differences between analog and digital acquisition:- Analog acquisition in modern detectors is realized by the following chain: analog detector unit, detector A/D converter, detector processing unit, detector D/A converter, analog cable, Clarity A/D converter (Colibrick, U-PAD2, INT9, etc.).
- The digital acquisition chain is much simpler: analog detector unit, detector A/D converter, detector processing unit, digital cable (USB, RS232, etc.), Clarity Control Module.
You can see at least three sources of problem in analog way: - Detector D/A converter
- Analog cable
- Clarity A/D converter (Colibrick, U-PAD2, INT9, etc.)
So there might be a significant difference between analog and digital signal quality. It depends on factors like:- Quality of detector D/A converter (analog output resolution may be worse than digital).
- Length and quality of analog cable.
- Proper cable connection (symmetrical, non-symmetrical).
- The absolute level of the analog signal (lower signal is more influenced by interferences from other laboratory devices).
- Proper A/D converted voltage range set (most typical problem is that a detector maximum signal is 10-100 mV only and Colibrick voltage range is set to 10 V. This leads to decrease of the voltage step resolution by 100-1000x!).
- Proper sample rate frequency set at all three converters, see FAQ How to set proper Sampling Rate?
- Proper peak width parameter.

Yes, you can. There are two possible intentions of using the sequence table for starting the acquisition: - Using sequence for manual injections
You could define parameters for a series of injections in advance in a sequence table and then inject them one by one manually. In such case, the start must be external (individual runs in sequence cannot be started from Clarity). - Using sequence for automatic injections without an autosampler
In such case, the sequence must be in the active mode (set through Sequence Options dialog). Sequence sends a command to the sampler (over a serial line or by digital output) and waits for the start signal from the detector (again over the communication line or digital input). Without an autosampler, it is possible to start the acquisition by using the digital input and output specified in Ext. Start Dig. Input and Ready Dig. Output section of the System Configuration dialog.
How to set digital input and output to start the sequence without an autosampler? - In case the injection is performed by some controlled valve or instrument (typically EAS analyzers) not supporting the Injection marker by digital output, the common solution when using the DataApex's A/D board is to interconnect the digital output set for Ready Out signal directly to the digital input set for Start In command. The digital input on the instrument starting the next run will be connected in parallel. With a controlled valve, the injection is then performed during the actual run by switching the valve (or valves) from the Clarity Event Table.
Events must be set in the Event Table accessible from the Method Setup dialog. .png)
- In case no A/D board is used and the devices are not offering those digital inputs and outputs (for example with Agilent GC 5890), the suggested workaround will be to use the DataApex Virtual Digital Input Output Loop (auxiliary device, requires A24 LC or A23 GC Control license) to simulate the input/output needed - (those are virtually interconnected).
For more detailed info refer also to Clarity Getting Started manual, chap. 6.
