Still some Ultramark in the ion source even after, um, a month or so...
(Ultramark is used to calibrate Finnigan mass spectrometers. It’s sticky, and tends to stick around even after repeated acetone washes. Really, the ultramark isn’t our main problem right now. Our real problem is a big mass of strong peaks from an unknown source.)
