ABSTRACT:
In a so-called Coulter-device with a first and a second chamber, a separag wall between them and a measuring aperture in the separating wall, through which particle-free electrolyte flows from the first chamber into the second chamber, and with first and second electrodes in the first and second chamber resp., at which a measuring impulse indicating a certain property (e.g. volume) is derived upon the passage of a particle, which is supplied to it through a supply capillary ending in front of the measuring aperture, the improvement consisting in means to supply additional particle-free electrolyte to the particle stream at and/or in the neighborhood of the downstream end of the measuring aperture to deflect those particles, which, after passage through the measuring aperture, travel backward to the same and cause error impulses.
