I am a new user to ICP-MS. I am having issues with the instrument failing the startup performance report. I know its about time that I clean my cones looking at the counts, however, just looking at the performance report values, nothing is standing out to me as "fail". I ran a performance report at the end of a calibration run yesterday, just to see the change over the hour or so it ran, and the count was MUCH different than before, and failed.
Does anyone have any ideas?
Hi Vaughn, if you go to Tools>Settings>Reporting>"Open Setting Dialog" next to Performance Check Settings you can see what the acceptable criteria is supposed to be (note that the units of sensitivity in your settings are cps/ppb but in the performance report they are "counts per 0.1s/ppb so there is a 10x conversion between them). Chances are, the failure is coming from your oxide ratio because the default setting is <1.8% and you're at 2.09%.
If there is any concern for the quality of your operation, please reach out to technical support at 1-800-227-9770 for recommendations on how to reduce oxide formation.
