Hello,
recently I run out of Tuning mix so I have prepared a new fresh one and now I have a problem with tuning my aparatus.
Tune mix was diuted 1:10 with acn + H20 + 3ul HP0321
I started the procedure with qtof system tune (poz and neg for both tof and quad) for 3200 mz. It passed the positive tune but for the negative - communicate that post tune calibration failed occured. Moreover the mass of 602 mz is much higher then others. I would like to ask for some advice
