| Application of robust statistical technique and Grubbs test method in inter-laboratory proficiency testing of data analyzing——Measurement of total Hg content in marine organisms as an example |

| Abstract: |
| This paper reported the application of robust statistical technique and Grubbs test method in inter-laboratory proficiency testing of total mercury measurement in marine organisms. Results showed that both of the methods performed well in determining the statistical outliers and laboratory’s performance ability in proficiency testing with participation of 51 laboratories. For both methods, their statistical results matched very well with each other. Compared with Grubbs test method, robust statistical technique is more scientific, intuitive and easier, and could be used for data analysis and testing proficiency evaluation among multiple laboratories. |
