采用离子色谱法测定饮用水中F-,并利用精密度偏性分析质量控制实验(AQC实验),检验分析方法的随机误差和系统误差,对质控水样进行重复性实验,绘制质量控制图,对采用的分析方法进行全面质量控制与评价。对其他同类实验化验人员全面掌握和正确运用分析方法,保证分析质量,具有重要参考意义。
Ion chromatography was used to determine F- in drinking water. The precision bias analysis quality control experiment (AQC experiment) was used to test the random error and systematic error of the analytical method. Repeated experiments were carried out on the quality control water samples to draw a quality control chart , Conduct a comprehensive quality control and evaluation on the analytical methods adopted. It is of great reference significance for other laboratories to fully understand and correctly use analytical methods to ensure the quality of analysis.
