Oxygen isotope concentration analyzer, and oxygen isotope concentration analysis method

摘要

PROBLEM TO BE SOLVED: To provide an oxygen isotope concentration analyzer and an oxygen isotope concentration analysis method, enabling the concentration of an oxygen isotope included in a plurality of samples containing water as the main constituent and differing in the concentration of oxygen isotope to be easily acquired with high accuracy.;SOLUTION: The oxygen isotope concentration analyzer has a 4-way selector valve 14(supply line switching unit), connected to sample supply lines 45-1, 45-2 provided in sample supply units 11, 12 (a plurality of sample supply units), for supplying a vaporized sample transported by one of the sample supply lines 45-1, 45-2 and a carrier gas into a multiple reflection optical absorption cell 55, and disposing of a carrier gas continuously supplied to the other of the sample supply lines.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
