5975 Series MSD Operation Manual 13
The 5975 Series MSD
The 5975 Series MSD is a stand-alone capillary GC detector for use with an 
Agilent Series Gas Chromatograph (Table 3). The MSD features:
• Local Control Panel (LCP) for locally monitoring and operating the MSD
• One of three different high vacuum pumps
• Rotary vane foreline pump
• Independently MSD heated electron-ionization ion source
• Independently MSD heated hyperbolic quadrupole mass filter
• High-energy dynode (HED) electron multiplier detector
• Independently GC heated GC/MSD interface
• Chemical ionization (EI/PCI/NCI) modes available
Physical description
The 5975 Series MSD is a rectangular box, approximately 42  cm high, 26 cm 
wide, and 65  cm deep. The weight is 25  kg for the diffusion pump mainframe, 
26  kg for the standard turbo pump mainframe, and 29  kg for the performance 
turbo pump mainframe. The attached foreline (roughing) pump weighs an 
additional 11  kg (standard pump).
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.
Vacuum gauge
The 5975 Series MSD may be equipped with a Micro-Ion Vacuum Gauge. The 
MSD ChemStation can be used to read the pressure (high vacuum) in the 
vacuum manifold. Operation of the gauge controller is described in this 
manual.
