Abstract
An apparatus which enables characterization of particles suspended in a liquid includes a housing with a mixing chamber and a collection chamber separated by a wall containing an aperture for passage of particles between, the mixing chamber and the collection chamber, the mixing chamber further containing a mixing member, a first electrode in the mixing chamber and a second electrode in the collection chamber for conduction of an electrical current through the aperture, a processor that is adapted for controlling the measurement sequence of the apparatus and detecting possible blockage of the aperture by detecting extended duration of the electrical pulse caused by the blocking particle, and upon detection of a blockage, reversing the liquid flow while mixing in the mixing chamber for removal of the blocking particle, and restarting particle counting.
