An innovative approach of sensitive and selective detection of trace amounts of chemical threat agents is presented in this work. The technology deals with semiconductor metal oxide gas sensors as a means of express gas detection, coupled with pre-sampling system, which is to improve sensitivity and selectivity of analysis. Examples for H2S, DMMP (phosphor-organic weapons simulant) and UDMH (highly toxic rocket engine fuel constituent) sensor detection with aided by pre-sampling system are given. The issues of sensor and adsorbent materials selection and their working parameters are discussed.
