Abstract
A particle detector includes: a flow cell having two chambers (A) and (B) communicating with each other via a through-hole, the chamber (A) having an inlet for a sheath liquid and the chamber (B) having an outlet for a waste liquid; a sheath liquid supplier; a nozzle for ejecting a particle-containing specimen with a tip portion of the nozzle being disposed at an appropriate position in the chamber (A), the nozzle being disposed coaxially with the flow cell and movable in an axial direction; an air cylinder for reciprocating the nozzle in the axial direction so as to switch between a sheath flow state for allowing the specimen and the sheath liquid to flow through the through-hole and a non sheath flow state for allowing only the specimen to flow through the through-hole; and a pair of electrodes for detecting a particle in the specimen when the specimen passes through the through-hole. Also, a particle analyzing apparatus including the particle detector is disclosed.
