Peak Purity: Relative Standard Deviation of the Match Factor (RSD Match)

The relative standard deviation of the Peak Purity Match Factor indicates its homogeneity over the entire course of the peak.

Calculation is analogous to the Relative Standard Deviation of the PPI (RSD PPI). Instead of the PPI values, the corresponding match values are used. Divide the standard deviation by the average of all match values (Match avg) and multiply the result by 100%. The result is the relative standard deviation of the match factor (RSD Match) in percent.
