CONTINUOUS MEASUREMENT OF BOD

摘要: PURPOSE:To suppress the change in BOD component a standard solution and generation of slime pipeline, measuring method using diaphragm type oxygen electrode microorganism comprising membrane, by adjusting pH org. substance-containing to predetermined value. CONSTITUTION:A cell 5 is attached lower parts 3 2 membrane. A buffer B, specimen S, solutions C1-C3, washing N air are supplied according process preset control circuit 8 such as microcomputer value S calculated on basis output current 2. Each an aqueous glucose-glutamic acid mixture thereof adjusted about 2-3. By these solutions, each eliminated even long-time continuous measurement within pipeline suppressed can be measured continuously.
