I have a problem where the baseline of my mass spectrum (top chromatogram in Google drive photos) randomly goes nuts. I know it's a problem downstream of the column because my FID chromatogram (2nd chromatogram from top) always looks good. When I look at the m/z in the noisy part of the baseline, it appears to be uniformly distributed among all m/z values. For reference, the two peaks between 2.4 and 2.8 are the only peaks that are supposed to be there.
I have made no changes to the instrument recently that could have caused this. Please let me know if you have any idea what could be wrong. Thanks in advance for the help!
