1. A spectral analysis device comprising:
a measurement unit that measures a sample spectrum of the target sample; and
an analysis unit that analyzes the sample spectrum,
wherein the spectral analysis device identifies a compound contained in the target sample,
the analysis unit has a library processed with an arithmetic processing before measuring the sample spectrum of the target sample, the library has a plurality of compound groups to which the compound is classified,
the sample spectrum is a rough spectrum obtained earlier than obtaining a complete spectrum which can pinpoint the compound in the target sample,
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, and
the analysis unit comprises an analysis display part, the analysis display part displays, 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.
