The 5977B Series MSD
The 5977B Series MSD is a stand-alone capillary GC detector for use with
either an Agilent 7890B Series or an Agilent 7820 GC. The MSD features:
• An optional JetClean system for cleaning the ion source in place under vacuum
• WEB User Interface (WUI) for locally monitoring and operating the MSD
• A turbo vacuum pump with one of four different foreline pumps or a
diffusion vacuum pump with a Pfeiffer DUO 2.5 foreline pump
• Four different types of independently heated EI sources available:
• Standard source in SS material
• Standard source in Inert material
• XTR source
• HES
• Turbo pump models with 7890B GCs are field upgradeable to CI (PCI/NCI)
modes. The upgrade adds an independently heated CI source, reagent gas
MFC and plumbing, and CI tuning calibration
• Independently MSD heated hyperbolic Quad
• HED EM
• Independently GC heated GC/MSD interface
Physical description
The 5977B Series MSD housing is approximately 41 cm high, 30 cm wide, and
54 cm deep. The weight is 39 kg for the diffusion pump mainframe, 44 kg for
the standard EI turbo pump mainframe, and 46 kg for the EI/CI turbo pump
mainframe. The foreline (roughing) pump weighs an additional 11 kg
(standard pump), and is usually located on the floor behind the MSD.
The basic components of the instrument are:
• Frame/cover assemblies
• Vacuum system
• GC interface
• Electronics
• Analyzer
