| Abstract: | 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%. |
