A new flow system for quantitative analysis and sorting of small particles, particularly biological cells, was developed. Multiparameter analysis is made of fluorescent stained cells as they flow in a liquid suspension through a unique flow chamber. Electrical and electro-optical sensors measure cell volume, single or two-color fluorescence, and light scatter to determine cell discrimination. A laser beam is used to excite cell fluorescence and light scatter. Sorting is accomplished by breaking up the emerging stream into uniform droplets and sorting those conforming to preselected standards as determined by the processed signals. Drawings are given of the Model 71 Multiparameter Signal Processing Unit used with the system. A detailed description of this system was published in the September 1973 issue of ''Review of Scientific Instruments.''
