A method and an apparatus for flow type particle image analysis

摘要: PURPOSE:To change over a measuring mode without changing the magnification of an optical system and to make image analysis efficient by method wherein flow cell in which size passage direction beam light for sample liquid can be changed is used, flow-rate ratio cleaning adjusted adjusted. CONSTITUTION:A flow-type particle-image analytical apparatus constituted 100 changed, photographing part 101, particle 102, detection 103 detects arrival position laser particles flow-system control 124. A central 29 supplies signal 124, sheath S1 S0 adjusted, thickness changed. That, say, fixed high magnification, reduced according depth field when measured small, increased order ensure number samples large. Consequently, labor time are reduced.
