Apparatus for counting viable particles in liquid in real time, dialysis fluid monitoring system and purified water monitoring system using the apparatus, and method of counting viable particles in liquid in real time

摘要

A viable particle counting apparatus 77 includes devices 10, 70, 2. The device 10 radiates a light with a predetermined wavelength toward a liquid containing a detection target. The device 70 reduces a Raman-scattered light emitted from the liquid out of lights emitted due to an interaction of the light radiated by the device 10 with the target or the liquid and selects an autofluorescence light emitted from the target. The device 2 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 device 70. The device 10 radiates the light with a wavelength that causes the autofluorescence light and the Raman-scattered light to be different in peak wavelength.

主权项

1. A viable particle counting apparatus comprising:
a light emitting element which radiates a light toward a liquid containing a detection target, a wavelength of the light causing a peak wavelength of an autofluorescence light emitted from the target irradiated with the light and a peak wavelength of a Raman scattered light to be different from each other; an optical filter which reduces transmission of the 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 by the light emitting element and transmits the autofluorescence light emitted from the target; and a determining device 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 optical filter.
