Introduction
Overview
The 5975T LTM GC/MSD is a stand-alone instrument combining
a GC and an MSD (
). The instrument features:
•
LTM GC column with rapid heating and cooling capabilities
•
Two capillary guard columns to minimize contamination of
the LTM column
•
Local Control Panel (LCP) for locally monitoring the
instrument
•
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 split/splitless 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 5975T LTM GC/MSD may be equipped with an optional
external vacuum gauge. Installation of the gauge controller is
described in this manual. Operation of the vacuum gauge is
described in the
5975T LTM GC/MSD Operation Manual.
