I recently bought Clarus 500 with Vici 6 way gas sampling valve for Natural gas analysis. (Porapak R packed column, manual PPC, TCD,FID) I use totalchrom navigator 6.3.2 software for data acquisition and stuff. Sample injection timed event is coded GSV1 or GSV2 on the instrument. but in the totalchrom software this timed event is missing but instead V1, V2 (valve 1,2) exists. When i use V1 timed event and inject, the it just went flat without any peak. Can anyone explain me how these timed events work on GC with GSV and how to install GSV one to totalchrom software.

Thank you
