Normalization to the RPT internal standard improves the accuracy of the RIF calibration curve for IMS (n=8 microspots). Relative error was calculated using unweighted (1/x0) linear regression. QC accuracy is reported as the average of the 8 microspots using the difference from 100% of the absolute value of the percent error.
