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.
本发明涉及一种分析仪,用于现场连续测量物质的生化需氧量,该分析仪包括一个流路(202),被分析物质流经该流路(202),所述流路(202)包括至少一种与物质相互作用降低其
氧气浓度的细菌群。
根据本发明,分析仪的特征在于,回路(202)包括一系列由所述细菌定殖的聚合物支架(212),该回路可使物质以必要和连续的方式与每个聚合物支架(212)接触。
