If your GC has a Flame Ionization Detector, it will not be active and any injections of samples will have no data collected.

If you are using hydrogen as a carrier gas then you will not have any chromatograms of separated analytes. No data.

You could have damaged columns if no carrier gas were flowing in them.

Hopefully the hydrogen is only used for detectors.

we use varian cp 3800 and it has FID luckily ther were no samples being run at that time
we use helium as the carrier gas and hydrogen is only for FID
my concern is will there be any problem with the coloum

and what if hydrogen was not there along with carrier gas not being there what would happen.

and sorry what should i do now i have turned the hydrogen cylinder on my supervisor has said just leave it for a while and run blanks

thanks a lot

Don't run any samples.

Turn on the hydrogen gas for the FID fuel and light your detectors.

After a couple of minutes the baselines should be stable and quiet.

Then carry on as if nothing happened.

As long as you had helium flow there should be NO problems at all.

best wishes,
