Latest Patents

One of Kenichi Mishima's latest inventions is an imaging mass spectrometer. This device generates ions by irradiating a sample with a laser beam and performs mass spectrometry of the ions. The imaging mass spectrometer includes a laser irradiation unit that emits the laser beam toward the sample, a condensing optical system that condenses the laser beam, an image acquiring unit that captures a condensing state checking image, and a display unit that shows this image on a screen.

Another notable patent is a chromatogram data processing system featuring an impurity detector. This system includes a differential chromatogram creator, a purity curve creator, and a determiner. The differential chromatogram creator calculates a differential coefficient of an absorbance spectrum and creates a differential chromatogram that illustrates temporal changes. The purity curve creator generates a purity curve that reflects changes in the degree of similarity of a spectrum to a reference spectrum, taking noise components into account. Both the differential chromatogram and the purity curve are displayed in a superposed form on a wavelength chromatogram.
