ABSTRACT:
Method and apparatus for characterizing a population of cells or particles such as blood cells or viruses by automatic means in a flowing stream which comprises: Novel suspending and dispensing means; controlled dispensing of a plurality of portions of the sample population; modification of the suspending milieu, mixing each portion with a different test reagent to elucidate a particular character of the sample; novel electrical separation means; separation of components of said mixture into different streams by said separation means; means for serially measuring properties of at least one of said separated streams to provide a series of measurements relating the reaction of the population to a plurality of different reagents for detailed characterization of said population.
Method and apparatus for characterizing liquids by automatic means in a flowing stream by reaction with specific binding sites on a population of cells or particles employing novel electrical separation means to separate components of the reaction mixture into separate streams, followed by measurement of at least one separated component stream.
