New sensor for Hydrogen Cyanide

Membrapor (Switzerland) has successfully developed a sensor for Hydrogen Cyanide (HCN). The HCN/C-100 exhibits an exceptionally short response time of t₉₀ < 20 s. With a sensitivity of 600 nA/ppm and a very stable baseline it is perfectly suitable for measurements in the lower ppm-range. This sensor is meant for the use in HCN monitors to protect workers for accidental releases of hydrogen cyanide gas. The HCN/C-100 is suited for use in the extraction of precious metals such as gold and silver, in electroplating, metallurgy and in the production of a wide range of organic chemicals, e.g., acrylonitrile, methyl methacrylate, and adiponitrile that are used in producing synthetic fibers and plastics.

The cross-sensitivity of the HCN/C-100 to carbon monoxide and to hydrogen is only 2% and the sensor life expectancy is 2 years.
