Abstract: A total organic carbon measuring instrument including a measuring unit composed of, integrated together, organic substance oxidation part (24) and carbon dioxide separation part (20) and conductivity measuring part (34), control unit (40) and data processing unit (41). In order to enhance the accuracy of conductivity measurement, the control unit (40) is constructed so as to stop feeding of a sample water at the time of oxidation of organic substance and carry out feeding of the sample water at the time of sample water moving to the organic substance oxidation decomposition part (20) and carbon dioxide separation part (24). The data processing unit (41) is constructed so as to measure the total organic carbon concentration on the basis of conductivity at the time of arriving of sample water irradiated with ultraviolet rays of which relative intensity is a given value or higher at the carbon dioxide separation part (24).

Abstract: To provide a flow cell that is free from liquid leakage and excels in chemical resistance. There is provided a preferred form of flow cell comprising flat-plate glass substrate (3); adherent fluororesin sheet (5) having a groove as flow channel (7) made by cutting machining; and glass substrate (1) as lid member furnished with through-holes (9, 11) as fluid inlet and outlet at positions corresponding to both end portions of the groove. The fluororesin sheet (5) is interposed between the glass substrates (1, 3) and, while heating at a temperature not lower than the melting point of the fluororesin sheet (5), pressurized so that the glass substrates (1, 3) are bonded together by the fluororesin sheet (5) per se. Flow channel member (17) is constructed by the glass substrate (3) and, bonded thereonto, the fluororesin sheet (5).
