Abstract

The invention relates to a device for examining particles in a liquid to be examined, comprising a flow passage through which the liquid to be examined is moved. The flow passage has at least one inlet through which at least one sheath fluid flows into the flow passage such that the at least one sheath fluid forms at least one sheath flow in the flow passage. The device further comprises a wave generating device for piezoacoustically generating sound waves which propagate through the flow passage transversely to the flow direction of the liquid to be examined and form wave nodes on a monitoring plane such that particles to be examined of the liquid to be examined are moved onto the monitoring plane and accumulate thereon on the basis of the pressure effect of the sound waves in the transverse direction.
