| Abstract: | The metal clip loosed connecting the polarization electrode and the polarization cable of FID of GC-9790 because of high-temperature combustion oxidation, which led to increase of contact resistance and clearance discharge. It was the cause of decrease of sensitivity and increase of noise voltage. The troubleshooting method was put forward. |
