A selective detection of dangerous substances (for example of halogenated organic compounds (HOC)) in trace concentrations is often necessary in analytical chemistry and environmental analytics. In cooperation with meta Messtechnische Systeme GmbH and Jüke Systemtechnik GmbH, Fraunhofer IKTS developed a detector on the basis of thermal catalytic surface ionization (TCSI detector). A ceramic body combined with a heater is the core element of such a detector acting as a catalytically active media for ionization of gas species. The achieved sensitivity to chlorinated hydrocarbons (CHC) is comparable with the sensitivity of ECD. The detection limit is < 10-9 mg.
Advantages of the detector are high reproducibility of data, long-term stability and reliability, compatibility with different types of GC columns and devices, cost-efficient production and simple handling.
