摘要
本文选用可变内参比法原理,用钢铁主体元素Fe作内标,用Ful校准技术校准标准工作曲线,用Type校准技术作为样品测试结果的实时在线校正。文中考察了影响分析信号强度最显著的入射功率、观测高度和载气流量三个操作参数,并对方法的准确度、精密度及检出限进行了讨论。
This paper studies the direct determination of P,Si,Mn,Cu,Cr and Ni in steels with the changed internal standard.The standard curves are standardized with FULL STANDARDIZATION,and the results of the sample are calibrated with TYPE STANDARD in time.The signal intensity influenced by RF power,observation height and sample gas folw is discussed.Results obtained for the determination of every element in steels are satisfactory.The RSD is less than 0 5% and the recovery is about 96—103%.The detection limit is about 0 002—0 07%.
