Reverse library search
Process of comparing a subset of the peaks in the mass spectrum of an unknown compound with peaks present in the library mass spectrum. Any peaks in the mass spectrum of the unknown compound that are not in the library spectrum are disregarded.
Note: A reverse library search measures the extent to which the peaks in a reference spectrum are present in the unknown spectrum and is more effective than a forward library search when peaks arising from two or more components are present in the unknown spectrum
