AS + LC set - Active Sequence

In LC systems, the autosampler typically governs the timings. The eventual pump gradient and detector programs are set independently. Any autosampler that is used in the Active Sequence without an AS Control module must be synchronized with Clarity by cables. The INn starting cable should be plugged into the synchronization output (INJECTION) of the autosampler, and the OUTnR cable should be plugged into the synchronization input (READY) of the autosampler.

The autosampler will initiate the injection after its input contact has been closed ①. After the injection, the autosampler will close the INJECTION contact ② , and the command to start acquisition will be given directly back ③. When using additional devices (Detectors, LC Pumps, etc.) it is recommended to connect these devices independently to other digital outputs of the A/D converter ④. Each device will then need a dedicated row in the Event Table (Fig "Event Table for starting detector and pump from Clarity".) to be started or stopped by Clarity.

Note:

The labels on the input and output contacts may vary depending on the type of the autosampler.

Note:

When the detector or pump start inputs are connected in parallel to the Clarity start input, make sure to ground the device properly.

The start output, mapping of Clarity to individual digital outputs of the Colibrick A/D converter, can be set in the bottom-right corner of the System Configuration dialog, see Fig "System Configuration". Use the following settings.

System Configuration LC set

Events to start additional detectors and pumps from Clarity must be set in the Event Table accessible from the Method Setup dialog. In the most typical setup (shown in Fig "Wiring of the autosampler in an LC set without the AS Control module") use the setting as displayed in Fig "Event Table for starting detector and pump from Clarity".
