高分辨电感耦合等离子体质谱法测定地球化学样品中的36种元素
Determination of 36 Elements in Geochemical Samples by High Resolution Inductively Coupled Plasma-Mass Spectrometry
摘要
Abstract
An analytical method for the simultaneous determination of Li, Be, P, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Rb, Sr, Nb, Mo, Cd, In, Sb, Cs, Ba, Hf, Ta, W, Tl, Pb, Bi, Th, U, Na2O, MgO, A12O,, K2O, CaO and TFe2O3 in geochemical samples by High Resolution-Inductively Coupled Plasma-Mass Spectrometry (HR-ICP-MS) has been developed. Samples were decomposed using HF-HNO3-HC1O4, and the residue was dissolved with aqua regia. The 36 elements in the solution were then determined directly by HR-ICP-MS. The optimal determination isotope and appropriate resolution for the 36 elements were selected to avoid the main spectra interferences from polyatomic ions and double charged ions. The detection limits (6a) of the method were 0. 002 -2.031 (Xg/g for trace elements, and 10. 0 - 100 jig/g for major elements ( DF = 1000). The relative standard deviation (RSD) was less than 10% (re = 12). The method has been applied to the determination of 36 elements in national geochemical standard reference materials and the analytical results were in agreement with certified values.关键词
