The 5975 Series MSD

The 5975 Series MSD is a stand-alone capillary GC detector for use with
Agilent Gas Chromatographs
• 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. Installation of the gauge controller is described in this
manual.
