Tune report for ICPMS 7900

Hello,

Agilent check the peak widths at 10 % and the usual range is between 0.65-0.8.  The semi-autotune is for a partial tuning.  If you only want to tune one mode.  In your case you work with both gases I recommend performing full autotune to adjust for both gases.  When you set a limit into the tune check you don't tune for that limit.  It's a parameter to evaluate the quality of the tune. 

Usually, we recommend using 1ppb tune solution 5185-5959 for the autotune.  Unless you use ISIS3 (where the dilution for tuning is 10ppb) the dilution is 1:10. Using another range of autotune solution will affect the peak width and prevent the correct performance evaluation of the instrument. 

We usually check everything is NoGas. For gases we have sensitivity range to account for performance of the instrument.  The method 200.8 prevent the usage of gases for autotune and stipulate that the ICPMS peak width must do 1amu at 5%. EPA 6020 is a better reference if you want to use gases for tuning.  

Hope this helps.

Unfortunately the Auto Tune will not be the solution.

The Mass Axis is set during the Startup Tests (Resolution/Axis), which are run after the Plasma start.

I would recommend, to run these Test every Day. 

The Software then aims for a Peak Width of <0.8 at 10%. If this doesn't fit with your needs, you have to "override hardware settings" in custom tune, but i strongly do not recommend this, unless you know exactly what to do.
