Abstract
A microbial particle is accurately counted in distinction from a non-microbial particle. A preceding-stage irradiation sectionirradiates a sample as fluid with ultraviolet light at a preceding stage of a microbial particle counter. The ultraviolet light is ultraviolet light having a deep ultraviolet region, the ultraviolet light increasing the fluorescence intensity of a first autofluorescence substance in the microbial particle. The microbial particle countermeasures light intensity in a first wavelength range including the fluorescence wavelength of the first autofluorescence substance. In addition, the microbial particle countermeasures light intensity in a specific second wavelength range. Further, the microbial particle countercounts the microbial particle in distinction from a non-microbial particle in the fluid based on the measured light intensity in the first wavelength range and the measured light intensity in the specific second wavelength range.
