Hey there again,

Just a bit of background info: I’m running a 7890B on OpenLab Chemstation C.01.10[201] and I have an annoyance I’d like to eliminate. When I open a newly run (as in unintegrated) chromatogram Chemstation will often load up a different calibration from the one I current have loaded. For example, I have calibrations for both PCB and pesticide quantitation. But after loading the pesticide calibration and pest chromatogram it will switch back to a PCB calibration. This gets really irritating and I’d like it to stop. It’s clearly something I’ve done but I’m unsure what that is.
