ANALYSIS METHOD FOR COMPONENTS DERIVED FROM FLORA AND FAUNA IN MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an analysis method for components derived from flora and fauna in a material containing substances derived from the flora and fauna capable of analyzing a large number at once in a short analysis time by a fixed method, irrespective of kinds of samples, without involving a dangerous experiment of introducing a radioactive isotope or the like.;SOLUTION: In the method for calculating a content of the substances derived from the flora and fauna in the material containing the substances derived from the flora and fauna, the material containing the substances derived from the flora and fauna, and the substances derived from the flora and fauna are burnt respectively to be converted into carbon dioxide, the obtained carbon dioxide is reduced to be graphitized, a ¹⁴C (A) amount of the material containing the substances derived from the flora and fauna, and a ¹⁴C (B) amount of the substances derived from the flora and fauna are measured by accelerator mass spectrometry, and the content of the substances derived from the flora and fauna in the material are calculated based on a ratio A/B thereof.;COPYRIGHT: (C)2006,JPO&NCIPI
