According to this, we determined 40 elements in geochemical byICP-MS, 21elements by ICP-OES and 49 elements by ICP-OES/MS: Thesemethods were specialized with low detection limits, high precision, goodaccuracy and high speed.

• 采用简单的酸溶解样品的方法溶解样品，在仪器最佳测定条件下用ICP-MS测定了样品中40个元素和用ICP-OES测定了样品中21元素，最后在ICP-MS和ICP-OES的折中条件下，测定了样品中含量不同的49个元素。
