Hi,
Thank you for your help in advance.
I found a leak in my 7890GC -MS system, I did a "front inlet leak check" from GC keypad the service mode. The pressure was the default 10psi, column flow 1 ml/min. However, the final result showed the total flow was below 0 and the column flow was higher than 1.
I appreciate any suggestions.
Thanks!
