Abstract

Apparatus for use with a particle analyzer apparatus, in which particles in fluid suspension are passed through a defined electric current path between fluid masses located on opposite sides of a wall, and in which pulses reflecting changes of electrical impedance in the trajectory, attributable to the passage of a particle through it, are supplied to an electrical device externally located for its detection, said apparatus further including a first container containing a mass of fluid that maintains said particles in suspension, and a structure, including said wall, is arranged to define at least one thin opening of known dimension, and at least one pair of electrodes placed on opposite sides of the opening and electrically connected to said electrical apparatus externally located: characterized by a series of second containers, each of them adapted for co The said fluid having said fluid and each of said second containers having a first wall, an opening in said first wall, whose first wall has its outer surface in contact with the fluid mass of the first container and the opening located at the point of said contact to allow the flow of fluid from the said first container only through said opening to the second container, and an electrode that contacts the fluid of the second container and includes an electrical conductor extending to the exterior of the second container to establish a terminal connection for the externally located electrical appliance, an electrode in said first container extending to the outside thereof to establish a common terminal connection for the externally located electrical appliance, the interiors of all the seconds being electrically isolated, containers cited with respect to the inside of the p first container and each other, except by means of said openings, by virtue of which the only electrical and fluid paths between them are produced by means of said openings.
