英语翻译
Quantiﬁcation was performed using modiﬁed,matrix-based isotope dilution calibration covering the concentration range of 0.50–100 ng/mL.The limit of detection,calculated using replicates of blank and low level spiked samples,was 0.66 ng/mL and the relative standard deviations were between 6.89 and
14.9%.The relative recovery of melamine was 101–106%.This method was tested for viability by analyzing samples collected from the general US population.Melamine was detected in 76% of the samples tested,with a geometric mean of 2.37 ng/mL,indicating that this method is suitable for reliably detecting background exposures to melamine or other chemicals from which it can be derived.

使用阳离子进行定量分析,以矩阵同位素稀释校准覆盖范围0.50–100毫微克/毫升进行检测,使用复制的空白表格和少量加料试样,计算结果为0.66毫微克/毫升,相对标准偏差在6.89 and14.9 %之间.三聚氰胺的相对回收率为101–106%.,对美国普通人群采集样本就该方法的可行性检测,76%的样本发现三聚氰胺,几何平均为2.37毫微克/毫升,以三聚氰胺或其他化学品及其来源检测,表明这一方法是可靠的.

这个有用的方法是利用了阳离子。艾德以矩阵为基础的同位素稀释校准覆盖范围0.50–100毫微克/毫升。检测，计算使用复制的空白和低水平样品，为0.66毫微克/毫升的相对标准偏差介于6.89和14.9%。相对回收率为101–106%三聚氰胺。这种方法是测试的可行性，通过分析采集的样本来自美国的总人口。三聚氰胺被发现76%的样本，一个几何平均为2.37毫微克/毫升，表明这一方法适用于可靠地检测背景接触三...
