Abstract
A waveform analytical devicewhich analyzes a target waveform which is a chromatogram or an optical spectrum includes a waveform division unitconfigured to divide the target waveform into a plurality of partial waveforms, a determination unitconfigured to determine whether each of the plurality of partial waveforms of the target waveform is a peak portion using a learned model created by machine learning using a plurality of sets of a plurality of partial waveforms created by dividing a reference waveform having a peak portion whose position is known, and a classification unitconfigured to classify the target waveform into a peak region where the peak portion continues and a non-peak region other than the peak region based on a determination result from the determination unit.
