Any help would be really appreciated.
Edit: We have an agilent 5975 MS

I lucked out and there was nothing on the source/quads/detector. I had a 73 where the rough pump regurgitated into the diff pump and the diff pump into the chamber a bit. there was a residue on the chamber walls and some crud inside the triode guage tube. I got that all clean, replaced the foreline pump with an E2M2 with a trap so that won't happen again. Just methanol and MeCl2 worked for me. If it is just diff pump fluid it is glycol based and should be soluble in methanol.

I'm worried I might be facing this problem as well, does the "MSD Bakeout" method do anything to help or will that just make things worse
