Abstract
The validation of a method for the determination of total chromium in Fischer-344 rat feces by inductively coupled plasma optical emission spectrometry following a rapid, atmospheric-pressure microwave digestion is described. The performance of the method was evaluated over the concentration range of 5.00 to 200 μg Cr/g feces. Data for method linearity, accuracy, precision, digest stability, and storage stability are presented along with limit of detection and limit of quantitation data. Data from a cross-validation method for B6C3F1 mouse feces are also presented. Following validation, the method was applied to analyze samples collected in support of two chronic toxicological investigations.
摘要
描述了一种在快速常压微波消解后，通过电感耦合等离子体发射光谱法测定Fischer-344大鼠粪便中总铬的方法的验证。在5.00至200μg Cr/g粪便的浓度范围内评估了该方法的性能。给出了方法线性、准确度、精密度、消解稳定性和储存稳定性的数据以及检测限和定量限数据。还给出了B6C3F1小鼠粪便交叉验证方法的数据。验证后，该方法用于分析为两项慢性毒理学研究收集的样本。
