The Series 100 Thermal Conductivity Detector GC uses four sensing elements that are connected to form an electrical Wheatstone bridge circuit. These elements are miniature rhenium-tungsten filaments, which are mounted in a metallic cell block. A flow through type thermal conductivity cell is normally used in this analyser.

A diffusion type detector may also be fitted. This cell contains a sample and reference gas flow geometry. Two elements are installed in each flow system. An electrical current from a regulated power source heats the elements. Changes in thermal conductivity of the sample gas result in an output voltage change.

We work closely with each client in order to ensure that all aspects of the application are understood. Then our applications design team will design a solution specifically with the application in mind. All our systems can be designed for corrosive applications and are manufactured with corrosion resistance materials.
