Analyte 2000 (tm) is a 4-channel, single wavelength fluormeter

The Analyte 2000 is a 4-channel, single wavelength fluorometer optimized for performing evanescent-wave fluoroimmunoassays that was developed in conjunction with the Naval Research Laboratory for biomolecule detection. This low-power, microprocessor-controlled instrument provides parts-per-billion sensitivities to biochemical species, such as proteins, viruses, bacteria, and spores, by monitoring antibody/antigen reactions on tapered glass waveguides. The instrument is controlled from a remote computer leading to a system size of only 20 cm L x 8.5 cm H x 11.2 cm W. The Analyte 2000, coupled with a separate fluidics box, has been flown and operated in small, unmanned air vehicles (UAVs) using a remote RF link to a ground-based portable computer.

The Analyte Adapter is a small optoelectronics module that serves an an interface between the Analyte 2000 and the inexpensive, injection-molded polystyrene waveguides developed for use with the RAPTOR fluoroimmunoassay system.
