three crazy peaks
Posted: Mon May 21, 2012 3:03 pm
Hi everybody
Today I tried to run FID checkout sample on GC 5890 W/O EPC connected with Chemstation A.10.02 but I could get three crazy peaks
first one is big size,a second one medium size and a small one.I was getting repeatidily three peaks, I mean when first group of three peaks ended just after that started to come out second group
of three peaks and again the same three peaks.
It seems smth like chemstation option because even when I didn’t inject any sample but just pressed start on GC KEYPAD it was the same situation,
Before injection the baseline was zero,I think it must be smth above zero and below 20pAb , am I right??
The detector lit and it was ok, the only thing that was not ok was purge vent because on the method it must be 40ml/min and in fact it was smth like 250 ml/min
Have you had any similar issue like this??
i appreciate every thought.
