Hello,
I wonder if I can use a pre-run command/macro to be executed in chemstation C.01.07 "Run time Checklist", for on/off activation of an external valve? I want to flush gas sample tubings as well as the loop on a gas sampling valve with proper amount af sample gas from a tedlar bag before injection, using a mirco pump connected as an external valve to the 7890B GC.
The gas samples are analyzed by the 7890B GC using sequence runs in chemstation.
Does anybody have a solution? How do I program a pre-run command for run time checklist? Where can I find the commands?
With kind regards -
Lars
