Abstract: Systems and methods for multiple analyte detection include a system for distribution of a biological sample that includes a substrate, wherein the substrate includes a plurality of sample chambers, a sample introduction channel for each sample chamber, and a venting channel for each sample chamber. The system may further include a preloaded reagent contained in each sample chamber and configured for nucleic acid analysis of a biological sample that enters the substrate and a sealing instrument configured to be placed in contact with the substrate to seal each sample chamber so as to substantially prevent sample contained in each sample chamber from flowing out of each sample chamber. The substrate can be constructed of detection-compatible and assay-compatible materials.

Abstract: Methods for detecting a target polynucleotide sequences are provided that utilize a probe having a target-complementary segment and a detectable tag. By cleaving the detectable tab and associating the tag with a tag complement coupled to an electrode, an electrochemical signal can be detected that is related to the presence of the tag:tag complement complex.

Abstract: A spray reactor for flue gas desulfurization, particularly suitable for steam generators, uses a plurality of flue gas inlets and complementary nozzles to spray an alkaline reagent into the flue gas, including means to maintain the gas velocity in said gas inlets in response to generator turndown by varying the cross-sectional area of flow of the waste gas into the reaction zone.

Abstract: A spray reactor for flue gas desulfurization, particularly suitable for steam generators, uses an atomizing disc to spray an alkaline reagent into the flue gas. Concentric inner and outer annular passages around the disc convey the flue gas, the outer passage flow being controlled by a series of dampers adapted to maintain a relatively constant flow velocity in the inner passage in response to turndown of the generator load.
