An automated particle sorter having a fluid flow path, which places single biological particles in an optical cuvette. An exciting light irradiation system having a light source emits a source of light through the cuvette. The light excites a fluorescent substance present on the particle, and the emitted light is detected by a light detection apparatus containing at least two detection elements for measuring the fluorescence emitted from the fluorescent substance. A light separation element separates the fluorescence from the exciting light. A data processor compares the signal received from the fluorescent light; and from the background autofluorescent signal, and according to pre-set parameters, controls the position of a collection conduit between two set points. The first being a collection set point for the collection of objects having a first phenotype and the second being a set point for the collection of objects having a second phenotype.
