MEASURING CELL, ANALYSER, PROCESS, AND COMPUTER PROGRAM PRODUCT FOR MEASURING BIOCHEMICAL OXYGEN DEMAND (BOD)

摘要

This invention refers to an analyser to measure, preferentially in-situ and in a continuous manner, the biochemical oxygen demand of a substance, comprising a flow circuit (202) through which the analysed substance flows, said circuit (202) comprising a collection of at least one type of bacteria that interact with the substance decreasing its oxygen concentration. According to this invention, the analyser is characterised in that the circuit (202) comprises a series of polymeric supports (212) colonised by said bacteria, being the circuit so adapted for the substance to enter into contact with each polymeric support (212) in a necessary and consecutive manner.
