区域地球化学调查样品分析方法是确保分析数据质量的最主要因素。以电感耦合等离子体质谱（ICP-MS）和X-射线荧光光谱仪（XRF）联合测定新疆某地区区域地球化学调查样品中的V、Cr、Cu、Zn、Co、Ni、Ba、Ti、Mo、W和Pb共11种元素，并将ICP-MS和XRF测定同批样品的结果进行了比较，指出不同元素的最佳分析方法，并评价了各分析方法的精密度与准确度，建立了一套科学的适用于区域地球化学调查样品分析的方法配套方案，本方法检出限和精密度均符合DZ0130.4-2006及补充说明中1∶5万化探样品测定标准要求。经国家标准物质验证，结果与标准值相符。 ICP-MS和XRF配套方案具有快速高效、灵敏度高的特点，可进行大规模多元素同时分析，适用于地球化学填图样品测试。

It is the most important factor to ensure the quality of analytical data for analysis method of the regional geochemical survey samples.In this paper,11 mineral elements(V,Cr,Cu,Zn,Co,Ni,Ba,Ti,Mo,W, Pb) of the regional geological survey samples in a region of Xinjiang were jointly determined by Inductively Coupled Plasma Mass Spectrometry and X-ray Fluorescence Spectrometer.The results of same batch samples for ICP-MS and XRF were compared,and the best analysis method for different elements was optimized,the analytical method precision and accuracy were evaluated too.Finally,a set of scientific matching program was established which apply to analysis the regional geochemical survey samples.The detection limit and the precision of the method meet DZ0130.4-2006 and supplemental instructions for 1∶50 000 geochemical samples standards. The reliability of the method has been tested by elements determination in Standard Reference Materials and the results are in agreement with the certified values.The matching program (ICP-MS and XRF) is rapid and high sensitivity,and it can be used to geochemical mapping samples analysis.
