摘要
自采地表水样品,通过加标制备成分割水平样品对开展22家实验室参加的实验室间比对。分别采用加标回收率范围统计、单个样品浓度稳健统计和分割水平检测样品对稳健统计三种方法对比对结果进行评价,分析三种评价方法的差异。
Since the adoption of surface water samples were laboratories participated in the inter--laboratory comparison. of a single sample concentration and split level test sample analyze the differences of the three methods. prepared by spiking into a split level samples for carrying out the 22 Respectively, the scope of the recovery rate statistics, robust statistics comparison of three methods of robust statistics to evaluate the results.
