摘要
在实际检测工作中 ,通过制作质控图控制方法的精密度和准确度 ,有效地控制了系统误差和随机误差 ,试样的回收率为 97～ 10 2 % ,相对标准偏差 2 5 9% ,实际样品测定结果较好。
This paper introduces the application of analytic quality control in actual monitoring. Quality control chart can help improve the accuracy and precision, and effectively control the system error and random error. The recovery rate of experimented sample is 97%-100%, with relative standard deviation of 2.59%, and the determination result for actual sample is better.
