Abstract:
A method and apparatus for detecting pathogens and particles in a fluid in which particle size and intrinsic fluorescence of a particle is determined. The classification of particles as biologic or inert particles using one or more thresholds is described.

A method and apparatus for detecting pathogens and particles in a fluid in which particle size and intrinsic fluorescence of a simple particle is determined.
Abstract:
A method and apparatus for detecting pathogens and particles in a fluid in which particle size and intrinsic fluorescence of a simple particle is determined, comprising a sample cell; a light source on one side of the sample cell for sending a focused beam of light through the sample, whereby portions of the beam of light are scattered at various angles by particles of various sizes present in the sample area; a particle size detector positioned in the light path for detecting a portion of forward scattered light; a pair of fluorescence detectors positioned off axis from the beam of light; and a pair of elliptical mirrors positioned such that an intersection of the incoming particle stream and the light beam are at one foci of each ellipsoid, and one of said pair of fluorescence detectors lies at the other foci.
