Molecular formula : MW : CAS :
nature : hydrophobic polymer materials (eg PTFE) as the adhesive electrode materials, according to the principle of fuel cells produced with porous and some waterproof, the better guide electric, high surface area and high activity of the catalytic activity of an electrode. Atmospheric pressure in the gas and electrolyte in Micropores in a state of equilibrium, to form a stable gas-liquid-solid three-phase interface, the control of certain potential under the conditions of keeping electrochemical reaction. Easy to use and suitable for continuous monitoring and prolonged analysis. Have been used to the atmosphere of CO, H2S, NO, NO2 mining and the environment HCN, hydrazine, alcohol and some phosphorus vapor harmful substances measured. GC also be used as the detector.
