I have a problem with my GC8890, which is new. However, it has been not using for several months due to staff shortage and workload. The ASL used to work perfectly fine and after changing the inlet, it bent the needles. I change the ASL to the back inlet and run some blanks to make sure that it's alright to run. However, the baseline is so bad. It keeps rising and dropping, then some ghost peaks appear. I have changed the inlet, gold seal, O-ring. I performed the instrument blank runs again and the baseline is still bad.
