Hello! I'm new to GC; apologies in advance if this is a silly question.
I'm trying to apply a column compensation to a method. I'm using an Agilent 8890 GC with OpenLab CDS software. I searched the manual (https://www.agilent.com/cs/library/usermanuals/public/usermanual-gc-operation-8890-g3540-90014-en-agilent.pdf) but have not had success in applying a column compensation. I think I must be missing something.
I'm able to collect the the column compensation signal in the software. However, when I go to update my method to use the compensated signal, it throws an error at me saying the signal doesn't exist. I *am* able to manually substract the signal, which may just be what I have to do. But reading the manual makes it sound like there should be an automatic way to record the compensated signal.
Am I missing a step? I've collected the comp signal in the same method; I'm only updating the method to use the comp signal afterward (see pics below).
