How to check the TCD detector broken or not?

[LUXIAOXIAO]

I tried measure the resistance and I can hear the clicking sound. Is there any other way to check？
Thanks!

Do you get a signal when you run a standard?

Hi,

Thanks for your response and help.
When I turn on the TCD detector, the signal turn from straight line to noise. When I increase the mass flow rate from 18 to 25, the noise position changed from about 0.1 to 0.2. I don't have standard gas, I just use 2 percent oxygen in Ar. There is no peak. I used 2 percent C3H6 in Ar, still no peak.

Another question, will the reference and make up gas flow rate affect a lot? I just wanna see a peak.

Thanks!

How are you introducing your sample gas to the GC?

Six way valve, this valve works since I used it for FID detector and there is peak.thanks!
