THEORY OF OPERATION

See Section 1.7, the "Glossary" section of this manual, for definitions of some of the
terminology used in the following explanations.
1.6.1 Analyzer Detector
The Analyzer detector subsystem is a thermal conductivity detector that consists of a balanced
bridge network with heat-sensitive thermistors in each leg of the bridge. Each thermistor is enclosed
in a separate chamber of the detector block. One thermistor is designated the reference element and
the other the measurement element. A schematic diagram of the thermal conductivity detector is
shown in Figure 1-2.
