Analyzer Design
2.1 Overview
The standard ACCUCHROME (Figure 2-1) consists of two compartments. The upper
compartment is referred to as the ‘chromatograph oven’, and houses the components
involved in the chromatograph analysis process. The 10 port valve (and 6-port valve, in High
Speed Heating Value Analysis analyzers), the chromatograph column(s), and the thermal
conductivity detector (TCD) are described further in Sections 2.2 and 2.3. A heater maintains
a constant temperature within the oven, which is critical for proper separation of the sample
gasses and the stability of the detector.
