ICP-MS 7850 AutoTune fail


My performance report is ok. But AutoTune before my batch fails everytime with error message "Auto tune failed because sensitivity is too low". Sample introduction system was cleaned and checked, but it didn't help. What else can cause such error? I cannot perform any data acqusition.

  • Hi,

    You probably tried everything already, but what I would do in your situation is do a manual tuning in the nogas  mode or the Helium mode (whatever you are going to use) and see if you can get any counts for Li7, Co59, Y89, Tl205 (agilent tuning solution 10 ppb).

    Try changing all lenses (one at a time) to see if you can get higher counts.
