　　1BOD analyzer Microbial electrical method Biochemical oxygen demand BOD rapid analyzer Measurement principle

　　The LB-50A BOD rapid analyzer adopts the microbial electrode method, in which the microbial membrane is tightly attached to the surface of the oxygen permeable membrane of the polarographic dissolved oxygen electrode, forming the microbial electrode. The instrument adopts a flow measurement method, which means that the sample flows through the microbial electrode. The microbial membrane contains a large number of aerobic microorganisms, which are very active in aerobic and organic environments. The output current of the oxygen electrode is proportional to the concentration of dissolved oxygen. When a liquid without organic matter passes through the flow cell, the dissolved oxygen passing through the microbial membrane hardly decreases. When a solution containing organic matter passes through a circulation pool, microorganisms consume a large amount of dissolved oxygen, which is proportional to the concentration of organic matter, resulting in a corresponding decrease in dissolved oxygen passing through the microbial membrane. The dissolved oxygen electrode measures the change in dissolved oxygen concentration to calculate the BOD value.
