Abstract

Particles contained in a liquid sample are analyzed by moving the particles along a detection passage past a detector using a liquid flow in the detection passage. To reduce the time required for analysis of each sample, the sample is delivered at an input location at the upstream end of the detection passage by movement of a movable container carrying the sample to the input location. Immediately after the commencement of the delivery of the liquid sample, liquid flow is caused to occur in the detection passage. Washing liquid is supplied to the input location by a liquid supplier different from the movable container which carries the sample.
