Answer
All peaks from both the unknown and library spectra are used to calculate the Purity Score, which is used to assess how well a compound matches an existing library compound.
A high value indicates a high probability that the unknown spectrum has been correctly identified and does not contain peaks from additional compounds at a significant amount.
A lower value indicates that the match is less certain or additional fragment ion peaks from another compound are present in the unknown spectrum.
A purity score of 100 indicates all major peaks are present in both unknown and library spectra.
