PerkinElmer Thermal Conductivity Detector (TCD) with Add-On Kit for PerkinElmer Clarus 500 GC, 230V - N6520023

Thermal Conductivity Detector (TCD) with Add-On Kit for PerkinElmer Clarus 500 GC, 230V. Kit includes all necessary items to install the TCD into the instrument: detector, heater, sensor, heater block, 1/6 in. gas line, and flow controller pneumatics. How it Works. Balanced carrier flow is maintained through the analytical and reference channels. The filaments are electrically heated and assume a temperature dependent upon the thermal conductivity of the gas passing over them. When column effluent of a different thermal conductivity passes through the analytical or reference channel, the bridge circuit becomes unbalanced and gives rise to a signal that yields the chromatographic output.
