Introduction

5977B Series MSD Version

The 5977B Series MSDs are equipped with a turbomolecular (turbo) pump and
a choice of four foreline pumps or a diffusion pump paired with a Pfeiffer DUO
2.5 foreline pump. There are three types of electron ionization (EI) sources
available on the 5977B 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). A chemical ionization (CI) source includes a reagent
flow control system, a 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
