Abstract
A mass spectrum generation section () generates an original mass spectrum at a peak of a target compound based on data acquired through analysis on a sample. A background spectrum generation section () generates a background spectrum in accordance with each of a plurality of predetermined background acquisition conditions. A difference mass spectrum calculation section () obtains a difference mass spectrum by subtracting the each background spectrum from the original mass spectrum, and a spectrum similarity calculation section () calculates a similarity between each difference mass spectrum and a standard mass spectrum of a candidate compound selected from a spectrum library (). A compound identification section () identifies the candidate compound as the target compound if the highest similarity exceeds a predetermined threshold.
