PID Analyzers - Model TC-55 -Thermal Conductivity Detector (TCD)

The thermal conductivity detector (TCD) is a universal detector with a ppm to % level range. The detector is described below: The Model 55 has a thermal conductivity (TCD) cell with a sealed reference, a low voltage power supply, and a Wheatstone bridge with an electrometer. The electrometer output is 0-10 VDC. The customer needs a separate ADC channel to feed the electrometer signal into the GC’s data system. Alternately, PID Analyzers sells a data system (Model --) that will feed the signal into a separate PC. he TCD is sensitive (ppm) and a universal detector for most compounds. It has a wide dynamic range (>10⁵).
