Description
KWIK DRAW Hydrogen Cyanide Detector Tubes
- Range: 5 – 50 ppm with 2 pump strokes
- Range: 2 – 10 ppm with 10 pump strokes
- 10 per box
- 24-month shelf life
- No Interferences From: hydrogen, methane, ethane, propane, butanes, carbon monoxide, carbon dioxide up to 15 vol.% (n=2) or 3 vol.% (n=10), higher saturated hydrocarbons (e. g. hexanes, octanes), olefinic hydrocarbons (e. g. ethylene) aromatic hydrocarbons (e. g. benzene), halogenated hydrocarbons (e. g. trichloromethane, trichloroethylene), nitriles (e. g. acrylonitrile), carbon disulphide, acetic acid up to 1 vol.% (n=2) or 2000 ppm (n=10), ammonia, sulfur dioxide up to 1000 ppm (n=2) or 200 ppm (n=10), hydrogen sulfide, hydrogen chloride up to 300 ppm (n=2) or 60 ppm (n=10). Hydrogen sulfide, discolors the protective layer from white to brown, nitrogen dioxide up to 100 ppm (n=2) or 20 ppm (n=10).
- Interferences: Free halogens (chlorine, bromine) are not indicated but will decrease stain length of hydrogen cyanide indication even when concentrations correspond to measuring range of detector tube.
