PARTICLE ANALYZING DEVICE, PARTICLE ANALYSIS METHOD, AND PARTICLE ANALYSIS PROGRAM

Abstract: in analysis of a particle by a pta method, in order to enable each particle to be analyzed for each type while suppressing increase in size and cost of a device even in a case where excitation wavelengths of fluorescent markers or particles having property of autofluorescence overlap each other, a light irradiation unit () that irradiates a sample emitting fluorescence of a plurality of colors with excitation light, one or a plurality of filters () that transmits the fluorescence of the plurality of colors while cutting off excitation light, an imaging unit () having color identification ability to image fluorescence passing through the filter (), and an analysis unit () that obtains a diffusion rate due to brownian motion of a particle included in a sample from image data of fluorescence obtained by the imaging unit () and analyzes physical property of the particle are included.
