Fluorescence immunoassay for determining single or multiple analytes based upon a single measurement of fluorescence are described.

Time-resolved fluorescence immunoassay

A method and apparatus for time-resolved fluorescence spectroscopy is described in which laser light from a single pulse is used to excite fluorescent photons in a sample, which fluorescence is detected by a PMT optimized for linearity and response time to produce photoelectrons which generate a current at the PMT anode. This current is discharged through an R/C network to produce a voltage amplitude waveform which is converted to an optical image, intensified, stored and digitized. The digitized version of the optical image is processed in a data processor to calculate the true fluorescence impulse response.
