建立了一种电感耦合等离子体质谱法测定银菊珍珠胶囊中稀土元素的方法。利用该方法分析了国家一级灌木枝叶标准物质(GBW 07603)和国际柑橘叶标准物质(NIST1572)中的稀土元素,结果与标准值一致。该方法已被用于分析银菊珍珠肢囊样品中的稀土元素。
A method has been established to determine trace rare earth elements in Yinju Pearl Capsule by inductively coupled plasma mass spectrometry. Fifteen rare earth elements in SRM GBW 07603 and SRM NIST 1572 samples were determined by the developed method, and the determined values were in good agreement with the certified values. This method was utilized to determine rare earth elements in Yinju Pearl Capsule.
