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

    Aug 30, 2019An electron capture detector 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 of capturing electrons. The free electrons to be attached to the SF6 molecules are created by a radioactive source.
