Abstract

PURPOSE:To eliminate errors owing to flying back of particles by providing the 3rd electrode of a doughnut-like disc shape of the diameter equal to that of a micro-hole on the inner side of a detector of the micro-hole for detection of particles and applying voltage for controlling thereto. CONSTITUTION:A micro-hole 3 for detecting particles of a detector 2 is located below the liquid level of particle suspended liquid 1, and the liquid 1 is sucked into the detector 2 through the hole 3. Particles are detected by electrodes 11, 12 in accordance with the difference in electric impedances between the liquid and the particles. Further, the 3rd electrode 13 consisting of a doughnut-like disc is provided on the rear side of the hole 3, and voltage for controlling is applied thereto through the line by an electric power source 17. Then, the detector forms equipotential lines like 3 which narrow the range of detection and therefore the signals generated by flying back of the particles are eliminated.
