ABSTRACT:
An assay apparatus and methods employing total internal fluorescence to define a thin observed volume of a multi-phase suspension from which the suspended phase, because of its size and shape, is substantially excluded. Observations of the fluorescence of a known quantity of fluorescent material introduced into a known volume of the sample containing the observed volume permits quantitation of the volumes of the suspended and suspending phases.
