A preprocessor extracts a plurality of spectra to be processed, from an overall mass spectrum. A simulated spectrum generator having a learned model generates a simulated spectrum having a peak discriminating action, from each mass spectrum. A postprocessor generates a combined simulated spectrum based on the plurality of simulated spectra. A peak filter executes peak discrimination on a peak list using the combined simulated spectrum.

Mass spectrum processing apparatus and model generation method

A method of analyzing microparticle compositions and a microparticle composition analyzing device are capable of quantitatively analyzing the mass concentration of air microparticles online for each chemical composition. The particle ray of microparticles in an air sample is converged, and is irradiated onto a narrow domain of a capture body which includes a mesh-shaped structure for capturing the microparticles in the particle ray while removing surplus gas phase components, and the microparticles are captured. Then, the narrow region is subjected to concentrated irradiation of energy rays, and the microparticles that are captured by the capture body are vaporized, sublimated or reacted to yield a desorbed component, which is analyzed.
