Disposable cartridge for automatic and continuous water quality monitoring

Abstract

Provided is a disposable cartridge for use in assaying an analyte in an automated water quality monitoring analyzer comprising: (a)a platform; (b)array of containers for separately containing at least one reagent, a buffer and a freeze dried preparation of luminescent bacteria, said containers being mounted on said platform; (c)reaction chamber mounted on said platform and configured for being moved between said containers, such that said reagent, said buffer and said freeze dried preparation of luminescent bacteria are conveyed to said reaction chamber in a predetermined sequence such that light detectable by said analyzer is emitted; (d)fluid transferring means for fluid transfer and mixing between said containers, reaction chamber, and analyzer; (e)conveying means for moving said cartridge to predetermined positions within said automated water quality monitoring analyzer for enabling analysis of said analyte.

Description

Background technique [0001] Most analyzers include pumps, valves, piping, chemical reagents, sensors, data acquisition and data communication systems, and provide frequent, accurate measurements of laboratory quality. [0002] There is a long felt unmet need for disposable containment kits for use with automated water quality monitoring analyzers based on bioluminescent technology. [0003] US Patent 5,801,052 describes an apparatus for reconstituting dried bacteria, but does not provide a solution to the above-mentioned problem of biocontamination. [0004] US 2002 / 0054828 A1 describes an analytical device preferably in the form of a floating buoy having a removable sleeve containing consumable components for use in the analysis and a main body part, however not for use with sensitive biological reagents and bioluminescent bacteria. make an offer.
