| 10 | Its distinguishing documented practice is the release of the underlying chromatogram alongside the numeric result. A released chromatogram allows a reader to see peak shape, baseline, integration boundaries and the presence of minor peaks, none of which is recoverable from a single [[Area percent purity|area percent]] figure.{{r|usp1503}} | 10 | Its distinguishing documented practice is the release of the underlying chromatogram alongside the numeric result.
