本文所提出的方法适合于石英包裹体中微量金属元素的测定。加入适量的外加基体溶液可消除基体成分的影响,标准加入回收率为96—102%,测定下限可达到10~(-3)—10~(-10)克。
The proposed method is suitable for the determination of trace metal elements in quartz inclusions. The addition of the appropriate amount of matrix solution can eliminate the influence of the matrix composition. The standard recovery rate is 96-102% and the lower limit of determination can reach 10 -3 -10 -10.
