Abstract

A component analysis device includes a data acquisition circuit that acquires spectral data of an analyte containing components, the spectral data being obtained by measuring a spectrum of the analyte with a sensor, a type acquisition circuit that acquires information indicating a type of the analyte, a storage that stores a reference spectral data set including multiple spectral data of substances each of which is estimated to be included in the analyte, the reference spectral data set corresponding to the type of the analyte, and an analysis circuit that performs a parallel factor analysis by using, as input data, the spectral data of the analyte and the reference spectral data set.

Claims (31)

1. A component analysis device comprising:

a data acquisition circuit that acquires spectral data of an analyte containing components, the spectral data being obtained by measuring a spectrum of the analyte with a sensor;

a type acquisition circuit that acquires information indicating a type of the analyte;
