Abstract
A tandem arrangement of sensing zones is established by alternately arranged electrodes and dielectric plates, each sensing zone has a particle sensing aperture, through which microscopic particles in an electrolyte suspension pass and electric current flows. The apertures are aligned. This tandem sensing zone arrangement improves the signal-to-noise ratio of a particle analyzing apparatus in which it is employed.
