5977C Series MSD Version

The 5977C Series MSDs are equipped with a turbomolecular (turbo) pump and a
choice of three foreline pumps (Pfeiffer Duo, Pfeiffer MVP-070-3x, Agilent IDP-3
24V) or a diffusion pump paired with a Pfeiffer Duo foreline pump. There are
three types of electron ionization (EI) sources available on the 5977C Series
MSD, a standard EI stainless steel (SS) source, an EI Extractor (XTR) source
available on the Inert+ MSD model, and a high efficiency source (HES). The
optional 5977C chemical ionization (CI) system includes a positive chemical
ionization/negative chemical ionization (PCI/NCI) ion source, reagent gas flow
control system, CI calibration system, and other required hardware features. The
serial number label displays a product number that indicates what type of MSD
you have. (See
