I have an ICP-MS measuring metals in drinking water. Dissolved Ca precipitates on the cones and causes a decrease in instrument response quickly over time. For example, only 10 samples of high-Ca water will cause a 15% decrease in instrument response. I can follow the decrease in response by running check standards every 10 samples. Is there a way to re-calibrate the slope (or 'reslope') every 10 samples by re-measuring only one standard solution, instead of re-calibrating (10 cal standards) every 10 samples? Or is there another way to correct for drift?
Philip Larese-Casanova Drift correction procedures are the ones i have shared the links here with and am sure you will like them and connect them as well
In this Link you can see that the procedure is introduced that can mitigate the deleterious effect of low-frequency noisesoften termed driftson the precision of an analytical experiment.

Drift is a big issue in ICP.

Our old ICP-AES needs to be turned on at least 2-3 days before actual measurement to prevent drift
