ANALYSIS METHOD OF NOBLE METAL USING LASER ABLATION ICP ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an analysis method of a noble metal using a laser ablation ICP analysis method which quickly, correctly and quantitatively analyzes the noble metal, and facilitates a quantitative manipulation.;SOLUTION: The analysis method includes: the process S11 for weighing a sample containing the noble metal; the process S12 for blending a fusing agent with the sample; the process S13 for fusing the sample blended with the fusing agent; the process S14 for forming a lead button from the fused sample; an ablation process S151 for irradiating the lead button with a laser light, and partially converting the lead button into particulates; the process (S152) for carrying the particulate to the interior of an ICP analyzer by a helium (He) gas; and an ICP analysis process S153 for ionizing and analyzing the particulates.;COPYRIGHT: (C)2011,JPO&INPIT
