摘要
建立食用油中痕量硫丹与多氯联苯测定的双重净化-气相色谱法。通过分析FAPAS质控样品测定结果绘制的质控图,并参加橄榄油中农药残留与多氯联苯测定的国际实验室间比对考核,使用平均值-标准差控制图来监测检测数据的准确度和精密度,探讨质控图及国际比对考核在实验室质量控制中的应用。考核结果 |Z|=0.0,结果优秀。
A dual purification gas chromatography method for the determination of trace endosulfan and polychlorinated biphenyls in edible oils was established. By analyzing the quality control charts drawn from the results of FAPAS quality control samples, and participating in the international laboratory comparison examination of pesticide residues in olive oil and polychlorinated biphenyls, the accuracy and precision of the test data were monitored by means of mean-standard deviation control charts, and the application of quality control charts and international comparison examination in laboratory quality control were discussed. The value of |Z| was 0.0, and the result was excellent.
