1 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 two types of EI sources, a standard stainless steel
EI source and an extraction EI source available on the Inert Plus MSD model.
A CI ion source includes a reagent flow control system, a CI calibration
system, and other required hardware features. The serial number label
displays a product number (Table 1) that indicates what type of MSD you have.
