The CETAC ASX-8000 control module enables direct control of the ASX-8000 autosampler. The control is performed over USB. Direct control means that the autosampler can be completely controlled from the Clarity environment - all autosampler parameters can be sent to the sampler directly from the computer, the sequence table can be planned and edited in the Clarity software and the order of the individual vials is directed by Clarity. Specific methods may be assigned for different vials in the same sequence and particular method used for the given sample will be saved in the resulting chromatogram. The ASX-8000 autosampler control module works with the 1.12 or greater firmware revision. It is recommended to check the user manual of the autosampler for its operating principles and restrictions.
