    摘要: A microbial particle measuring apparatus includes: a light emitter configured to irradiate a fluid with light of a predetermined wavelength over a predetermined measurement time; a fluorescence receiver configured to selectively receive fluorescence emitted from particles contained in the fluid and output a signal having a magnitude corresponding to intensity of the fluorescence; a signal acquisition unit configured to obtain the signal output from the fluorescence receiver at regular intervals over the measurement time; and a determiner configured to calculate a slope of waveform of the signal obtained by the signal acquisition unit, and determine a concentration of microbial particles contained in the fluid using an attenuation amount of fluorescence intensity generated in a time period in which the slope in the measurement time is smaller than a predetermined value as an amount of attenuation derived from the microbial particles.

    摘要: There is provided an art capable of detecting viable particles in a liquid and counting the number of the viable particles even if there is an influence of a Raman-scattered light by water.
    There are provided: a light emitting means (10) which radiates a light with a predetermined wavelength toward a liquid containing a detection target; an autofluorescence selecting optical means (70) which reduces transmission of a Raman-scattered light emitted from the liquid out of lights emitted due to an interaction of the target or the liquid with the light radiated from the light emitting means (10) and transmits an autofluorescence emitted from the target; and a viable particle determining means (2) which determines whether or not the target contained in the liquid is a viable particle, based on a light obtained after the Raman-scattered light is reduced by the autofluorescence selecting optical means (70), and the light emitting means (10) radiates the light with the predetermined wavelength that causes the autofluorescence and the Raman-scattered light to be different in peak wavelength.

    摘要: The biological particle counter has a first circuit configured to generate a first signal corresponding to fluorescence from the biological particle in response to irradiated light. A measurement value obtainer is configured to obtain, from the biological particle counter, a voltage value of the first signal for a calibration particle obtained in such a manner that a fluorescence agent infiltrates into a surface of a polystyrene particle. A circuit adjuster is configured to use reference data indicating a correspondence relation between a fluorescence agent parameter value correlated to the content of the fluorescence agent and a reference voltage value of the first signal corresponding to the fluorescence agent parameter value, thereby specifying the reference voltage value of the first signal corresponding to the fluorescence agent parameter value for the calibration particle. The first circuit is adjusted such that the voltage value of the first signal for the calibration particle reaches the reference voltage value.

    摘要: A microbial particle is accurately counted in distinction from a non-microbial particle. A preceding-stage irradiation section 2 irradiates a sample as fluid with ultraviolet light at a preceding stage of a microbial particle counter 1. 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 counter 1 measures light intensity in a first wavelength range including the fluorescence wavelength of the first autofluorescence substance. In addition, the microbial particle counter 1 measures light intensity in a specific second wavelength range. Further, the microbial particle counter 1 counts 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.
