Flame ionization detector (FID)
FID flameout problems
When using pressure programming with large id columns (i.e. 530 ¿ columns) it is possible to blow the FID flame out if pressure (flow) becomes too high. If this occurs, either lower the pressure ramp or switch to a more restrictive column (longer and/or smaller id).
