Abstract: [PROBLEMS] To use in a carbon dioxide separation part a gas-permeable membrane capable of maintaining high-speed determination and to diminish the influence of interfering ingredients.[MEANS FOR SOLVING PROBLEMS] An apparatus which comprises: an organic-substance oxidation part in which organic substances contained in a sample water supplied are oxidized into carbon dioxide; a carbon dioxide separation part in which the carbon dioxide contained in the sample water treated with the organic-substance oxidation part is caused to permeate and come into a measurement water; and a conductivity measurement part in which the conductivity of the measurement water sent from the carbon dioxide separation part is measured. The carbon dioxide separation part comprises: a sample water channel in which the sample water treated with the organic-substance oxidation part flows; an intermediate water part in which an intermediate water having a higher pH value in a neutral region than the sample water flowing through the sample water channel is present; and a measurement water channel through which the measurement water comprising deionized water flows. The sample water channel is in contact with the intermediate water part through a gas-permeable membrane, and the intermediate water part is in contact with the measurement water channel through a gas-permeable membrane.

Abstract: [PROBLEMS] To increase the rate of gas transfer in gas exchangers.[MEANS FOR SOLVING PROBLEMS] A gas exchange chip comprises substrates (1,2); two flow channels (3,4) formed in the substrates (1,2) and each having an inlet port and an outlet port; and multiple grooves (9) interlinking the flow channels (3,4). The grooves (9) have the size of their sectional area predetermined and have at least a part of the internal surface thereof rendered hydrophobic so as to permit the transfer of gas component while inhibiting any liquid passage. A sample water containing carbon dioxide is caused to flow through one of the flow channels (3) while pure water is caused to flow through the other flow channel (4) to thereby transfer the carbon dioxide contained in the sample water into the pure water.

Abstract: Disclosed herein is a method for measuring total organic carbon without the influence of nitrogen components. The method for measuring total organic carbon includes the steps of: (1) adjusting the hydrogen ion concentration of sample water to between pH 4 and pH 6; (2) decomposing organic matter and nitrogen compounds contained in the sample water into carbon dioxide and nitrous acid, respectively, through oxidation and; (3) making the carbon dioxide permeate into measuring water via a gas-permeable part 5a; (4) and measuring the electric conductivity of the measuring water to determine the total organic carbon content of the sample water.
