Abstract
PURPOSE:To realize not only an increase of measurement precision but a reduction of the time of measurement, by giving a contact between a certain amount of specified component gas and a reaction liquid in a state under which it is consecutively renewed in a certain flow rate and then detecting the variation of the reaction liquid in a state under which the reaction liquid reaches a specified gas concentration. CONSTITUTION:The sample gas is controlled to a certain flow rate by an air pump 7, a flow rate meter 8 and others and then sent into the hollow tube 1 through the sample gas injection port 3 via the intermediate cell 9 containing the dilute sulfuric acid solution to absorb the basic gas that does not react with the sample gas and disturbs the measurement. At the same time, the reaction liquid 10 is injected through the reaction liquid injection port 2 so that it flows down by a quantitative pump 11, etc. with formation of a liquid film on the inner wall of the hollow tube, and then the liquid 10 has a contact with the sample gas. The liquid 10 has a pH change to be equal to the pressure of carbon dioxide component in the sample gas, and the caused potential is detected by the pH electrode 6 to know the amount of carbon dioxide in the sample gas. In such a way, a measurement of a high reproducibility is made possible in a short time.
