    Hi,

    your Mass Axis looks quite nasty. I would suggest to rinse the system thoroughly and then do the Axis/Resolution again.

    It seems that you have a massive Lead contamination. Maybe your Tune Solution is contaminated as well.

    So after exchanging all solutions and rinsing the system with 1% Nitric for a while, run it again. 

    You also can run this setting with a 10ppb Tune Solution, in order to set the Axis to the right settings.

      

    Best of Luck
