Measurement
The Method Setup - Measurement tab describes in detail the measuring conditions and determines the duration of an analysis.
Method Setup - Measurement
The Method Setup - Measurement dialog will open with the method name displayed in the title bar when invoked from the Instrument or Single Analysis window. While performing a multi-detector measurement, this tab is common for all signals.
Contains the description of the method. When opening the method, the content of this field is displayed in the Description field of the Open Method dialog after the method is selected.
Describes (informational purposes only) the column being used.
Describes (informational purposes only) the mobile phase used.
Indicates (informational purposes only) the mobile phase flowrate.
Indicates (informational purposes only) the mobile phase pressure.
Contains (informational purposes only) the detector characteristics.
Describes (informational purposes only) temperature parameters.
Sets automatic termination of an analysis after the time set in the Run Time field.
Specifies the duration of analysis. After the appointed run time has been reached, the analysis will automatically be terminated and processed. The possible time interval is between 0.2 - 9999 minutes. Enable Autostop option must be checked for this field to be editable and functional.
Note:
The Run Time field must be set for all methods used in an active sequence since the time determines the cycle duration.
An optional note (for informational purposes only).
Enables external start synchronization using an external signal from Digital Input on the A/D converter. Three types of the External Start/Stop operation are possible:
- Start Only - The external signal only starts analysis. Any external signals coming during the analysis will be ignored.
Note:
The Start Only operation mode is automatically preselected upon creating a new method.
- Start - Restart - The external signal terminates the analysis in progress and at the same time starts a new one. The first signal starts the analysis, the second signal terminates it and at the same time starts a new one. This is known as “the continuous measurement”.
Note:
The Start/Restart operation mode can not be performed for majority of directly-controlled instruments.
- Start - Stop - The external signal starts and stops an analysis. The first signal starts the analysis, the second signal stops it, third signals starts a new analysis etc.
The externally synchronized instrument may react on contact closure or contact opening. Clarity allows both options.
The station reacts to a voltage change in the relevant controlling input from low (< 0.7 V) to high (> 3 V), or in other words, to an opened contact.
