有效实施盲样考核的探讨

Effective Blind Sample Appraisal

为探讨盲样考核和加标回收试验的实施方法,提高其在实验室能力评定活动中的有效性,待现场试验项目及盲样相关特性量的适宜性确认后,建立盲样考核信息表和作业指导书;简易盲样及加标样品参考相应项目的分析方法制备。现场试验项目对应盲样相关特性量适宜性的确认,可去除不适宜的项目;盲样考核信息表和作业指导的建立可排除非实际能力的误判,该方法可提高盲样考核和加标回收试验在实验室能力评定活动中的有效性。

The paper intends to explore an effective blind sample appraisal and spike recovery test for better laboratory capacity assessment.After confirming the suitability of field test items and blind sample characterizations,blind sample appraisal information tables and operating instructions were established;simple blind samples and spiked samples were prepared according to corresponding items.Such confirmation procedures could expel inappropriate items;and the establishment of information tables and operating instructions could exclude misjudgments due to non-actual ability.This method can enhance the effectiveness of blind sample appraisal and spike recovery test in laboratory capacity assessment.
