<p><P>PROBLEM TO BE SOLVED: To provide a device of measuring a global warming gas component in liquid capable of using a liquid containing the global warming gas component as a measuring sample, and having excellent accuracy and rapidity. <P>SOLUTION: In this measuring device 1, a test liquid including, for example, methane is supplied, and methane in the test liquid is extracted continuously into, for example, carbon tetrachloride so as to be equilibrated with the methane concentration in the test liquid, and an infrared ray is transmitted through carbon tetrachloride after methane extraction stored in a cell 5, and the infrared ray is filter-processed and detected by a non-dispersive infrared detector 8. Since the methane-containing quantity in the liquid can be measured by the measuring device 1 in this way, in-situ realtime analysis measurement becomes possible. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
