摘要： The present invention relates to an improvement in spectral analysis in spectrometry, particularly in a technique of spectral analysis by spectral classification at high speed.
A spectral analysis device 10 comprises: a measurement unit 20 that measures a sample spectrum of a target sample 30; and an analysis unit 40 that analyses the sample spectrum, and analyses a compound contained in the target sample 30, wherein the analysis unit has a library that is processed with an arithmetic processing in advance, the library has a plurality of compound groups to which the compound is classified, and the analysis unit further comprises an analysis display part 42, the analysis display part 42 displays, in real time, the compound group to which the compound belongs during analysis of the sample spectrum as the analysis progress or analysis result.

摘要： A spectrometer capable of providing information, to a measurer, necessary for determining whether a sample set to the spectrometer is a sample expected by the measurer or not before a main measurement includes a data processor and a display. The data processor calculates a preliminary spectral information of the sample based on at least n of a latest detected signal and a BKG information retained in advance, calculates and updates the preliminary spectral information based on at least n of the latest detected signal and the BKG information again, and repeats these calculations and updates. The display shows the preliminary spectral information that is calculated and updated in the preview display. The data processor starts integration of N (N>n) of the detected signal during a preview display of the preliminary spectral information, and acquires a spectral information of the sample.
