Abstract
Four hundred and sixty-six "blind" duplicate serum samples were analyzed for polybrominated biphenyls (PBB) by gas chromatography in two laboratories. As calculated by the regression model of Deming, the correlation coefficient for these 466 samples, whose values ranged from nondetectable amount to 1240 parts per billion was 0.9983. Prior to these analyses, the method was validated in both laboratories by using in vitro and in vivo PBB serum pools.
摘要
在两个实验室中，采用气相色谱法对466份“盲样”重复血清样本进行了多溴联苯（PBB）分析。根据戴明回归模型计算，这466份样本的值从检测不到到十亿分之1240不等，其相关系数为0.9983。在进行这些分析之前，该方法在两个实验室中均通过使用体外和体内PBB血清库进行了验证。
