An analytical method for determining wear metal elements directly by ICP-AES was proposed in this paper. The optimum condition was selected. The Conostan S-21 and Conostan 75 (oil-base standard samples) prepared by multi-element oil-base reserved standard samples were applied to make calibration curve. Oil samples were diluted 5 times by kerosene. The contents of wear metals in lubrication oil were determined by ICP-AES. The relative standard deviation (RSD) of all elements was less than 1%. In addition, the authors represented the analytical efficacy of Leeman labs multi-track profile ICP, and its rapid and accurate characters of simultaneous multi-element measurement.
本文提出了一种直接用ICP-AES测定磨损金属元素的分析方法。选择了最佳条件。采用多元素油基储备标准样品制备的Conostan S-21和Conostan 75（油基标准样品）制作校准曲线。油样用煤油稀释5倍。用ICP-AES测定润滑油中磨损金属的含量。所有元素的相对标准偏差（RSD）均小于1%。此外，作者还介绍了Leeman labs多通道轮廓ICP的分析效能及其同时多元素测量的快速、准确特性。
