The 5977C Series MSD
The 5977C Series MSD is a single-quadrupole GC/MS system for use with
Agilent 8890 and 9000 GCs. The MSD features (See Table 3 on page 16):
• 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 three different foreline pumps (Pfeiffer
Duo, Pfeiffer MVP-070-3x, Agilent IDP-3 24V) or a diffusion vacuum pump
with a Pfeiffer Duo foreline pump
• Five different types of ion sources available:
• Standard source in SS material
• Standard source in Inert material
• XTR source
• HES
• CI (PCI/NCI) source
• Turbo pump-equipped 5977C models, when used with an 8890 GC, are field
upgradeable to CI (PCI/NCI) modes. The upgrade adds a CI source, CI source
radiator for HES systems, CI flow module with an MFC, plumbing, and CI
tuning calibration.
• Independently MSD-heated hyperbolic quadrupole mass filter
• Independently MSD-heated ion source
• HED EM
• Independently GC-heated GC/MSD interface
Physical description
The 5977C 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
