用火花光谱或X射线萤光光谱测定合金中组分具有样品处理简单、快速、操作简便等特点。但两者都存在着严重基体效应。难以制备和试样组分相应的标准。因而影响测定结果的准确度。由于ICP—AES基体效应小,标准与试样的基体不必严格匹配,适于多组分同时测定,精确度高,准确度好等特点。因此近年来,在 Using spark or X-ray fluorescence spectrometry to determine the composition of the alloy has the advantages of simple, fast and easy sample handling. But both have serious matrix effects. It is difficult to prepare a standard corresponding to the sample composition. Thus affecting the accuracy of the measurement results. As ICP-AES matrix effect is small, the matrix of the standard and the sample do not have to be strictly matched, which is suitable for simultaneous determination of multiple components, high accuracy and good accuracy. So in recent years, at
