| Abstract: | 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. |
