Introduction

The GC/MSD

The GC/MSD features:
• LTM GC column with rapid heating and cooling capabilities
• Capillary guard column to minimize contamination to the LTM
• Local Control Panel (LCP) for local monitoring
• Choice of foreline pump - rotary vane (wet), scroll (dry), or diaphragm (dry)
• Heated electron-ionization ion source
• Heated hyperbolic quadrupole mass filter
• High-energy dynode (HED) electron multiplier detector
• Heated GC/MSD interface
• ChemStation control for operating the GC/MSD
Physical description
The 5975T LTM GC/MSD is a rectangular box, approximately 41 cm high,
60 cm wide, and 54 cm deep. The weight is 46.5 kg for the mainframe. The
attached foreline (roughing) pump weighs an additional 15 kg (standard
pump) for wet, and 4.5 kg for dry.
The basic components of the instrument are: the frame/cover assemblies, the
local control panel, the vacuum system, the EPC, the GC/MSD interface, the
inlet, the LTM column module, the electronics, and the analyzer.
Local control panel
The local control panel displays the status of the instrument, displays error
messages, and allows setting and display of some instrument parameters for
the Agilent 5975T LTM GC/MSD. These parameters are normally controlled
using the Agilent ChemStation.
Vacuum gauge
The MSD may be equipped with an optional external vacuum gauge. Operation
of the gauge controller is described in this manual.
