中文摘要:

      在能力验证试验中，采用微波消解-原子荧光光度法测定了化妆品中的砷含量，Z值为-0.81，|Z|<2，采用稳健统计"Z比分值"来评价和判定检测结果，结果满意.采用加标回收和精密度试验进行质量控制，并就如何提高试验准确度及需注意的问题进行了讨论.

英文摘要:

      The arsenic content in cosmetics was determined byatomic fluorescence spectrometry with microwave digestion method. The international general robust statistics "Z ratio score" is -0.81,|Z|<2,the proficiency testing is satisfactory. Standard spiked recovery test and precision were used for quality control. How to improve the accuracy of the experiment and the problems needing attention in the experiment were discussed.
