摘要
介绍GC-9790气相色谱仪的氢火焰离子化检测器由于燃烧室高温燃烧氧化作用,极化电极与极化电缆相连接的金属夹变形松动,导致接触电阻增大和间隙放电,使得检测器灵敏度下降并产生大的噪声电压。提出了故障的排除方法。
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.
