pusakcute85

Hi, I have encounter this problem for several time. The FID detector flame ignition on and off several time. I've already checked the FID jet and check the column connection to FID. No problem shows.

    Hi pusakcute85,

    I have updated the tags for better visibility . From the parameters above it should light and stay lit. You makeup gas is a little high and you may gain stability by lowering it to something like 10ml/min. The jet maybe partially restricted and this is hard to tell so I usually just suggest a jet change as a first pass. What model of GC do you have?

    Regards
