STABLE ISOTOPE RATIO ANALYSIS SAMPLE COLLECTION METHOD, STABLE ISOTOPE RATIO ANALYSIS METHOD, GEOGRAPHIC ORIGIN IDENTIFICATION METHOD, AND STABLE ISOTOPE RATIO ANALYSIS SAMPLE COLLECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a stable isotope ratio analysis sample collection method, stable isotope ratio analysis method, geographic origin identification method, and stable isotope ratio analysis sample collection device, which allow for making stable isotope ratio analysis in a nondestructive manner.;SOLUTION: A stable isotope ratio analysis sample collection method according to an embodiment of the present invention, comprises steps of; bringing a suction cup into contact with an object under measurement; discharging air inside the suction cup; filling inside the suction cup with an inert gas; allowing a measurement target component to diffuse from the object under measurement into the inert gas; collecting the inert gas containing the measurement target component; letting the inert gas containing the measurement target component flow through a filter so as to allow the measurement target component to be attached to the filter; and eluting the measurement target component into a solvent from the filter.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
