When using a GCMS duel column, when using one column at 1.2ml/min what should i do for the second column if it's on a deans switch (do i keep at same flow or lower? my service engineer has said drop it to 0.1-0.3ml/min but im scared of dmg to column

Hi
I guess that one column is connected with MSD and second column with any other detector..
both feed the detector, i will have it so one column is 1.2 and the other 0.3 so total flow to MSD is 1.5
Can you share picture of oven and columns connected with detector..
Hello it is better to have some extra flow coming from the pressure control module. i.e. C1 - 1.0, C2 - 0.3, R - 1.5 or something similar. Reason being better pressure control at the splitter.
Michael1993 , please set it at 2 psi (constant pressure mode) for the second column. Make sure that you configure the column correctly, inlet is either front inlet or back inlet, outlet is either MSD or other (0 psi).
