Hi everybody, hope someone can help me
I am new working in GC. We have an 7890A FID detector and we do splitless injections. And now we are having problems at the baseline, but not in all the samples, a hump appears sometime first was at minute 21, then minute 28 but then without doing anything it corrected, but now it is with an alarm that doesn't reach the pressure and at the last sample run there was a baseline drop. Finally it is working but at the post run send again the alarm.
