Abstract
In a method of monitoring specific microbe in water, a monitored object water is supplied into a flow cell provided in a particle size analyzer based on the laser diffraction method, and by irradiating a laser beam to the flow cell, a spatial intensity distribution of the diffraction and scattering light by a group of the particles contained in the monitored object water is measured to obtain a particle size distribution of the group of the particles. Accordingly, information relating to a possibility of an existence of the specific microbe with a known diameter in the monitored object water can be obtained.
Claims6
A method of monitoring an existence of a specific microbe with a predetermined particle diameter in a liquid, comprising:
- providing a particle size analyzer based on a laser diffraction method having a flow cell,
- guiding a liquid to be monitored into the flow cell,
- irradiating a laser beam to the flow cell in which the liquid to be monitored flows,
- measuring a spatial intensity distribution of a diffracted and scattered light of the laser beam,
- calculating a particle size distribution of particles existing in the monitored liquid from a result of the spatial intensity distribution, and
- comparing the particle size distribution of the particles in the liquid and the predetermined particle diameter of the microbe obtained in advance to judge if there is a material having the predetermined diameter in the liquid.
