GC-Pro TCD Introduction

Introduction
The GC-Pro TCD Analyzer is a microprocessor controlled digital
instrument incorporating a Thermal Conductivity Detector (TCD)
coupled with a gas separation column and switching valve designed to
measure the quantity of aromatic hydrocarbons present in a positive
pressure sample gas. Up to 8 channels of output are present for
measuring specific analytes in a sample stream. In using a thermal
conductivity detector after gas separation through a column, the range of
analysis is extended to include additional phase separable inert, or other
difficult to analyze gas phase components like N
2
, H
2
. etc. that are
present in a positive pressure sample gas.
The GC-Pro TCD Analyzer has multiple channels for measurement
with enhanced versatility and capabilities. Due to its flexibility, it is
vitally important that you refer to Appendix C for the specific factory
setup for your application.
The GC-Pro TCD features a modern user interface with a touch
screen front panel facilitating operation, calibration, data collection and
display. With the Ethernet connectivity feature, this new interface allows
the instrument to be operated remotely with a VNC software application
from another digital device whereby the analyzer can be accessed,
controlled, data displayed etc. as if the analyzer were physically present.
Although the analyzer arrives already setup for your specific
application, a gas chromatograph mode allows the user to program the
instrument for measuring different species present in the sample.
1.1 Main Features of the Analyzer
The GC-Pro TCD Analyzer is sophisticated yet simple to use. A
touch screen display on the front panel provides access all phases of
setup, calibration, operation, and troubleshooting on the GC-Pro TCD.
The main features of the analyzer include:
 Stable, accurate thermal conductivity detector for analyzing
inert gases and other species not amenable to flame
ionization detection.
