Title: ICP-MS count drop
Post by: Phil101 on August 07, 2017, 09:26:18 PM
Hello,

we experienced a drop in the number of counts for Mn after re-processing data from a week ago. There was no correction factor into account.

Simply by reprocessing the data with a slightly different calibration, the actual number of counts read dropped dramatically. Has anyone seen this happen before? What could be the explanation?

Please feel free to give ideas.
