Abstract

A flow cytometer and a method for determining properties of single cells or other particles including passing stream of particles through a zone of analysis where a light source directs a beam of light to perpendicularly intersect the stream of particles so that only a single cell is exposed to the light beam. An array of optical fibres adjacent the zone of analysis collects the light refracted by the cells as each cell passes through the zone of analysis. Each fibre is connected to a photomultiplier for converting the light to electrical signals which are analyzed by an electronic analysis unit to determine the particle properties. The angle at which the light is collected by said optical fibre is adjustable to permit more light to be collected to yield more information about the particle.
