The exhaust of the nitrogen generator is pointed towards the back side of QTOF and the rough pump is also at the back. I have noticed the temperature in the back of the QTOF is actually different, little warmer than the rest of the room. My question is, is this a valid potential reason for the observed mass deviation?
However, our service engineer is predicting it might be because of some component problem inside the machine.
