Hello all, has anyone ever seen their 922 reference mass change to 959.9 on the Agilent 6545XT? It only seems to happen in the tune mode when I am checking choosing the reference mass calibrant bottle (not tune mix), but during a normal method, the reference mass is back to 922. I am thinking it is some sort of adduct, but I'm not really sure what it might be? Any ideas or thoughts?
Thanks!
