【摘要】 <正>地质样品由于含成分复杂的多种难溶基体,很难找到合适的方法,在所有浓度范围内对其进行多元素同时分析。传统的湿化学分析法仅能进行主含量和浓度范围1%以上的元素分析,可分析的元素也十分有限。某些微量及痕量元素分析可采用比色分析法,更多采用的是光谱分析法,如电感更多还原

【Abstract】 Multi-element analysis of geologic samples is a difficult task due to its complicated component and inconvenience in sample preparation.In this paper,56 elements in geologic sample powder were determined by glow discharge mass spectrometry(GD-MS).The choice of conductive host matrix and the mixing ratio were discussed.Spectral Interferences has a great influence on the accuracy of analytical results for the some elements. The relative standard bias of 51 elements is 43.4% in average,indicating the fast survey analysis of geological samples without reference standard by GD-MS is feasible.Calibrated by solo standard,The analytical results of Li, Na,Mg,Al,Cr,Fe,Co,Pb concentration calibrated by solo standard are in good agreements with their certificated values.更多还原
