Check that the gas chromatograph FID igniter is illuminated during the ignition sequence.

Verify that the ignition offset is less than or equal to 2.0 pA.Chromatography vials

Check for leaks or partial blockage of the nozzle.

Check the gas chromatograph FID airflow rate. The ratio of hydrogen to air greatly affects the ignition. Non-optimal flow settings prevent flame ignition.

If the flame still does not ignite, there may be a large leak in the system. Large leaks can cause the measured airflow rate to differ from the actual airflow rate, resulting in non-ideal ignition conditions. Thoroughly inspect the entire system for leaks, especially at the FID.

Check the gas chromatograph column Chromatography vials flow rate.

Check for leaks at the gas chromatograph FID column fitting.

Make sure the gas chromatograph FID temperature is high enough to ignite (greater than 150 ° C).Chromatography vials
