The I-GRAPHX CA can be used for all tasks to detect and measure several components in any possible gas mixture. The gas separation technic (chromatography) will ensure that there will be no irritations by other components although they are very close to it. The dual channel thermal conductivity detector is an in-house development of I-GRAPHX GmbH. The detector is built in microchip technology (MEMS) and used the specific heat conduction of the different gases. This construction enables a fast measurement of specific gas mixture. This special design enables the unit to react very fast. While the sensor is glass passivated, it is protected against aggressive gases and can be used in harsh environment during long time. The device is very reliable, with no movable parts and will withstand vibration.
