Is there a way to arbitrarily insert a calibration in the middle of a run? The nature of our analysis is basically running discrete samples as part of a run over the course of a few days. Like any analysis, recalibration sometimes is necessary for a variety of reasons. The problem lies in that if I recalibrate during a run, the worksheet recalculates all the values. If a sample was analyzed shortly after the original calibration, I’d like to preserve those data, as they are likely closer to the true value. I realize I can start a new worksheet, but I’d rather just insert a calibration when I need to. I am also aware that I can set the method to include calibrations during a run, but as far as I can tell, that has to be determined before the run as part of the method and cannot be altered.
Which model ICPOES do you have and what is the version of software please?
