Dear QE-users,

In the method where full MS positive mode and PRM mode are used, we always get an incorrect auxiliary gas reading (41 instead of 25). This only happens in this method; other methods without PRM run without this message. All parameters seem to be correct. What are the possible causes of the problem in this method? Thank you in advance for the tips.

Already checked: tune files full ms & prm are identical, resetting the electronics helps the problem niet, so it seems to be method-specific.

Thank you in advance for the tips.
