I recieve a new Agilent 6850 last month, and when I want to analyse my sample it appears a problem. I think it's a leak on the split but not sure.
The baseline after the solvent peak goes under 0, and this isn't normal for this method
see below the chromatogram
The area are 4 times lower than another Agilent GC (one 6850 and one 7890).
I changed the septum / liner / O-ring / etc. Base maintenance was effectued but the problem persists. I can call the Agilent technician, but I want fix it by myself and understand the problem.
Method works perfectly on two other GC, so I know the problem went from the new GC and not from the method.
Carrier gaz: H2 / Split: 1/20
Can anybody help me?
Thanks
Jeremy
