Waters (Micromass) AutoSpec™

electron impact, magnetic sector, direct probe

The sample in a piece of glass capillary is inserted into the source (under vacuum) and heated.  The resulting vapors are bombarded with 70 eV electrons.  PFK, perfluorokerosene, is used for calibration. The purchase of the AutoSpec® was partially funded by NSF Award #CHE-9304546 to the Department of Chemistry.
