Device and method for determining and monitoring water toxicity

摘要

A device (1) based on discrete technology random access and direct reading for monitoring and analysis of toxicity in water using bacter ias and / or bioluminescent microalgae comprising: a) a module (2) storage aqueous sample; b) a module (3) storage of aqueous buffer; c) a module (4) dispenser; characterized by: d) a reaction tray (5) suitable to accommodate reaction cuvettes (6); e) washable sterilizable trays and housed in said reaction tray; f) a module (7) washing and sterilization of said reaction cuvettes (6), wherein the wash module includes a drain line and a connection to containers having receptacles solutions washing and sterilization; g) one or more modules luminometric measurement (8) arranged in predefined said reaction tray positions (5), wherein said module (8) luminometric measurement comprises a photomultiplier (18) and a beam (19) of fiber optics arranged in a predefined position of said reaction tray (5), said beam (19) optical fiber having a rectangular section and a surface substantially corresponding to the surface of said reaction cuvettes (6) on the side said reaction tray (5) and a round section on the side of said photomultiplier (18) and wherein the reaction tray (5) automatically rotates to alternately positioning each reaction cuvette for automatically measuring the light emitted by the suspension reaction, wherein the reaction cells have positions in the reaction tray, and the dispensing module is configured to combine bioluminescent bacteria with one or more aqueous buffers and one or more samples within the cuvettes in their positions in the reaction tray.
