Abstract

PURPOSE:To improve the measurement accuracy of particle counting by enveloping particle suspension with liquid which does not contain any particle. CONSTITUTION:Rectifying pellets 13 provided with space parts 11 and small holes 12 are mounted to a detector body 3 in such a manner that the space parts 11 align to detecting pellets 10 and are connected to rectifying liquid wells 16 by way of supplying passages 14 and liquid tubes 15. After rectifying liquid 30 which does not contain any particle, such as physiological slat soln. is filled in the space parts 11 is a slightly pressurized state, a positive pressure is introduced through apressure lead-in port 5 into the body 3, and the sample 28 which is particle suspension is ejected through fine pores 8. At the time when the ejected flow thrusts through the space parts 11, it is flowed into traps 21 by being surrounded by the rectifying liquid 30. At this time, particles are detected by the differences in the electrical impedance between the internal electrode 18 and external electrode 17 of the time when the sample 28 passes the fine pores 8. Thus, the rectifying liquid 30 prevents the inclusion phenomenon of particles, whereby the generation of unnecessary pulses is prevented and the accuracy of measurement is improved.
