    Abstract: A method of flow cytometry analyzes a stream of sample material having more than one fluorescing species. The method comprises the steps pf providing a plurality of intensity-modulated excitation light beams each being modulated at a respective unique frequency; directing the intensity-modulated excitation light beams to interact with the sample material; detecting fluorescence emission light from the sample material to provide signal information representative of detected light intensity versus time; and extracting a plurality of component emission signals from the signal information, wherein each component emission signal corresponds to a respective one of the modulated excitation light beams. Apparatus for implementing the method include flow cytometers and bulk sample analytical optical systems. The invention is helpful in determining species concentrations in cases where the fluorescing species have overlapping or substantially the same emission spectra.

    Abstract: An apparatus and method for analyzing liquid samples employs first and second bidirectional ports that permit liquids to be introduced to first and second liquid waveguide capillary cells at the same time. The direction of liquid flow through the apparatus and roles of components may be reversed to prevent or overcome obstruction by particulates and other debris. The apparatus and method can detect and map colored dissolved organic matter and can detect, discriminate and map algal species or algal blooms including red tide in an automated, unattended manner within large aquatic systems.

    Abstract: A portable spectrophotometric system for detecting one or more target substances. In a representative embodiment, a system of the invention has an optical grating, an array of photo-detectors, and a MEMS device having a movable plate positioned between the grating and the array. Light transmitted through a gaseous sample is dispersed by the grating and is imaged onto the movable plate, which has a plurality of openings corresponding to selected infrared absorption lines of the target substance. A small-amplitude oscillation is imparted onto the plate such that the openings periodically move in and out of alignment with the corresponding intensity features in the image, which modulates electrical signals generated by the corresponding photo-detectors. A lock-in signal processor analyzes the modulation pattern by comparing it to the pattern expected in the presence of the target substance. When a positive correlation between the patterns is established, the system warns the user about the presence of the target substance.
