  • Electron capture detector(ECD) method for sf6 gas gas

    50 secs readAug 30, 2019An electron capture detector (ECD) is used to detect SF6 with high sensitivity below 1 ppmv. This device makes use of the high electron attachment coefficient of SF6, i.e. the ability to capture electrons. The free electrons to be attached to the SF6 molecules are created by a radioactive source. The ECD uses a radioactive emitter, typically, a metallic membrane coated with the radionuclide nickel.

  • SF6 Gas Hazards and How to Avoid Them - WIKA blog

    3 mins readJul 31, 2020The best way to avoid SF 6 gas hazards is to continually monitor gas-insulated equipment for both quantity (to detect leaks) and quality (for current gas conditions). Then, when the gas has dropped below a certain level of purity, technicians can clean it. Here are just a few of WIKA USA’s innovative SF 6 gas solutions for greater safety and efficiency:
