I was wondering if there is a macro that can automatically calculate the %RSD for an analyte calibration curve in Chemstation B.04.03 version. Currently, I have to copy the entire calibration table to excel and have excel do the math. It would be wonderful if Chemstation could have it in the far right column on the calibration table. All i need it to do is take the standard deviation of the response factors and divide it by the average of the response factors and multiply it by 100. Anybody know if this is possible or if a macro exists that performs this task?
