ANALYSIS METHOD OF NOBLE METAL USING LASER ABLATION ICP ANALYSIS METHOD

PROBLEM TO BE SOLVED: To provide an analysis method of a noble metal using a laser ablation ICP analysis method which can perform quickly and correctly quantitative analysis of the noble metal, and facilitate a quantitative manipulation.SOLUTION: An analysis method comprises: a process S11 for weighing a sample containing noble metal; a process S12 for blending a fusing agent with the sample; a process S13 for fusing the sample blended with the fusing agent; a process S14 for forming a lead button from the fused sample; an ablation process S151 for irradiating the lead button with laser light, and converting a part of the lead button into fine particles; carrying the fine particles to the interior of an ICP analyzer by helium (He) gas (S152); and an ICP analysis process S153 for ionizing and analyzing the fine particles.
