The micro TCD has advantages for speed, accuracy, and reduced dead volumes. In combination with our microDELTA™ integration platform, the assembly and integration into a micro GC is done fast and at relatively low costs.

The micromachined TCD measures the thermal conductance of a gas by monitoring the resistance of a heated resistor in the gas flow. The chip contains a sample and a reference channel, and is either directly connected to the GC system chip, or to in/outlet capillaries in case of a separate component. The TCD can be driven at a constant temperature mode, or in a Wheatstone bridge configuration
