The 5977B Series MSD
The 5977B Series MSD is a single-quadrupole GC/MS system for use with
Agilent 8890, 9000, or 7890 GCs. The MSD features (See Table 3 on page 18):
• 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 5977B models, when used with an 8890 or 7890 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 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
