AS + GC set - Passive Sequence
The autosampler used in the Passive Sequence does not need the OUTnR digital output cable to be connected. All timings are controlled by the chromatograph and autosampler. Clarity performs only one analysis for each start signal received. Synchronization includes only external start of data acquisition in Clarity using the INn starting cable.
The sequence must be started in Clarity before the autosampler. The autosampler initiates the injection after manual start on the device. The sampler is synchronized with the GC by a signal wire (READY), allowing the next injection only after the GC gets to the READY state. After an injection, the autosampler will close the INJECTION contact ① and thus the command to start GC will be given ②. At the same time, the chromatograph will close the START contact ③ and thus the command to start acquisition will be given ④.
Caution:
It is necessary to set timings in the autosampler and Clarity to ensure the next injection will be performed after the previous run is finished.
Wiring of the autosampler in Passive Sequence
Passive Sequence must be used for example in the sets with Headspace autosamplers
Caution:
It is not recommended to use the Passive Sequence together with the Control modules.
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"
