Abstract
Particles flowed through a micro-channel are imaged by imaging means. Particle speed measuring means determines the particle speed from the image data. Particle counting means counts the particles flowed for a predetermined time. Particle size measuring means measures the size of the particles. The measurements of the particles flowed at a predetermined timing are managed by data associating means. With this, the speed, number and size of particles flowed through a micro-channel can be determined at a time, and associated data can be obtained.
