Other elements should have aconcentration below 0,2 %.NOTE High carbon concentrations, in combination with high Mo and Cr concentrations, could have undesirablestructural effects on the sample and could affect the determination of phosphorus and chromium, in particular.Matrix effects exist between the elements listed. To compensate for those inter-element effects, mathematicalcorrections shall be applied. A variety of computer programs for corrections is commonly used and included inthe software package from the manufacturers.【中国标准分类号】: H11【国际标准分类号】: 77_040_30;77_140_20【页数】: 32P.;A4【正文语种】: 英语
