Description
KWIK DRAW Phosphine Detector Tubes
- Range: 0.1 – 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, higher saturated hydrocarbons (e. g. hexanes, octanes), olefinic hydrocarbons (e. g. ethylene), aromatic hydrocarbons (e. g. benzene) up to 1 vol.% (n=10), sulfur dioxide, carbon disulfide up to 1000 ppm (n=10).
- Interferences: Arsine, stibine are indicated with lower sensitivity than phosphine. Hydrogen sulfide will be indicated by a yellow-brown stain, significantly lighter than phosphine stain and only one-half as long. Acetylene will no be indicated. Phosphine in acetylene gives a stain about twice as long as in air.
