Claim 18:
19. A spectral analysis method by using a sample spectrum of a target sample measured by a measurement unit, and an analysis unit that analyzes the sample spectrum to identify a compound contained in the target sample, the method comprising steps of:
measuring a rough spectrum by the measurement unit, the rough spectrum being obtained earlier than obtaining a complete spectrum that can pinpoint the compound contained in the target sample,
classifying, by the analysis unit, the compound contained in the target sample to a compound group by using a library processed with an arithmetic processing before measuring the sample spectrum of the target sample, and
displaying, in real time, the compound group to which the compound belongs during measurement of the rough spectrum as an analysis progress or an analysis result to an analysis display part of the analysis unit,
wherein the complete spectrum is obtained by repeating integrations at least several times to pinpoint the compound, and the rough spectrum is obtained by fewer integrations than a number of the integrations for obtaining the complete spectrum.
