日本分析化学学会开发了两种新的认证标准物质，JSAC 0402和JSAC 0403，用于分析痕量无机成分。材料通过了13种元素（Cd、Pb、As、Cr、Se、Cu、Zn、Ni、Mn、V、Hg、B、F）的浓度认证和7种元素（Cd、Pb、Hg、As、Se、F、B）的洗脱分析（环境部发布）的浓度认证。为了证明分析数据，进行了有17个化验室参加的实验室间比较工作。在对参与者报告的数据进行统计分析时，稳健方法中的z分数被应用于拒绝异常值，然后是通常的统计程序。该方法可为土壤中无机污染物分析的质量保证和质量控制提供参考。
The Japan Society for Analytical Chemistry has developed two new certified reference materials, (CRMs) JSAC 0402 and JSAC 0403, for analyses of trace inorganic components. The materials were certified for the concentrations of 13 elements (Cd, Pb, As, Cr, Se, Cu, Zn Ni, Mn, V, Hg, B and F) and for the concentrations obtained by the elution analysis (issued by Ministry of Environment) of 7 elements (Cd, Pb, Hg, As, Se, F and B). For certifying analytical data, an interlaboratory comparison exercise, in which 17 laboratories had participated, was carried out. In a statistical analysis of data that reported from participants, z scores in the robust method were applied to reject outliers, followed by the usual statistical procedure. The presented CRMs are expected to be useful for the quality assurance and the quality control in the analysis of inorganic pollutants in soil.
