Abstract
A particle counting apparatus for counting a total particle counting value contained in a liquid sample comprising, a flow cell in which the liquid sample flows, a light source for irradiating a light beam to the sample liquid in the flow cell, a detector for detecting pulse-wise signal scattered from the particles by the irradiating of the light beam, and a computer for obtaining the total particle counting value contained in the liquid sample as a counting value measured when the top end of the liquid sample is irradiated with the light beam and the plural particles in the top end does not overlapped in the light beam, multiplied by a coefficient.
