  • Publication number: 20230377116
    Abstract: A pre-processor applies a pre-process to an original mass image produced through mass spectrometry of a sample, to produce a model input image. An image quality converter has an image quality conversion model produced through machine learning based on a group of images produced by a scanning electron microscope, and produces a model output image through image quality conversion of the model input image. A post-processor applies a post-process to the model output image, to produce a mass image after image quality conversion.

  • Patent number: 11211150
    Abstract: 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.

  • Patent number: 9285298
    Abstract: 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.
