5977 Series MSD Operation Manual 13
The 5977 Series MSD
The 5977 Series MSD is a stand-alone capillary GC detector for use with an
Agilent Series Gas Chromatograph (Table 3 on page 14). The MSD features:
• Local control panel (LCP) for locally monitoring and operating the MSD
• One of two different high vacuum pumps
• One of three different foreline pumps
• Three different types of independently MSD heated electron-ionization (EI)
sources available: standard (stainless), inert, and extraction
• Optional chemical ionization (PCI/NCI) modes available that add a
chemical-ionization (CI) source, reagent gas flow controller and plumbing,
and CI tuning calibration
• Independently MSD heated hyperbolic quadrupole mass filter
• High-energy dynode (HED) electron multiplier detector
• Independently GC heated GC/MSD interface
Physical description
The 5977 Series MSD housing is approximately 41 cm high, 30 cm wide, and
54 cm deep. The weight is 39 kg for the diffusion pump models, 44 kg for the
standard EI performance turbo pump mainframe, and 46 kg for the EI/CI
performance 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: the frame/cover assemblies, the
local control panel, the vacuum system, the GC interface, the electronics, and
the analyzer.
Local control panel
The local control panel allows local monitoring and operation of the MSD. You
can tune the MSD, run a method or a sequence, and monitor instrument
status.
