玉米粉中脱氧雪腐镰刀菌烯醇的测定能力验证结果分析
目的 分析实验室对脱氧雪腐镰刀菌烯醇(deoxynivalenol, DON)的检测能力验证结果。方法 设计制备玉米粉中脱氧雪腐镰刀菌烯醇考核样品, 对样品的均匀性和稳定性进行检验。采用稳健统计法A对32家实验室提交的32个有效结果进行统计, 通过Z比分数评价实验室检测能力, 并对统计方式的合理性进行分析比较。结果 制备样品的均匀性稳定性符合能力验证样品要求, 32家实验室中31家结果满意, 总体满意率为96.9%。选择的统计方法合理, 统计结果正常。结论 绝大多数参加实验室玉米粉中DON检测能力良好, 个别实验室需加强内部质量控制。
Objective To analyze the proficiency test results for determination of deoxynivalenol (DON) of the laboratories. Methods Samples of deoxynivalenol in corn flour were designed and prepared, and the uniformity and stability of the sample were tested. Thirty-two valid results submitted by 32 laboratories were counted by robust statistical method, the testing ability of the laboratory was evaluated by Z score, and the rationality of the statistical method was analyzed and compared. Results The uniformity and stability of the prepared samples met the requirements of the proficiency testing samples, and the results of 31 out of 32 laboratories were satisfactory, with an overall satisfaction rate of 96.9%. The selected statistical methods were reasonable and the statistical results were normal. Conclusion The majority of participant laboratories are evaluated to have good detection ability of DON, while some laboratories need to strengthen quality control.
