质量控制图在土壤重金属的电感耦合等离子体发射光谱法测定中的应用

Application of Quality Control Chart in Inductively Coupled Plasma Emission Spectrometry of Soil Heavy Metals

质量控制图是以高等数学的概率论及统计检验为理论基础而建立的一种既便于直观地判断分析质量又能全面、连续地反映分析测试结果的波动状况的图形,是用于常规检测质量控制的一种有效方法。将质量控制图和空白值的检验结合起来,不仅可以实现检出限的检验,而且可以动态地控制试验的各个方面的条件。该方法的推广运用可以提高实验室的分析测试和质量管理水平,保证数据质量。

Quality control chart is an effective method used for routine testing quality control which is based on the probability theory and statistics test of higher mathematics and a kind of image convenient for intuitive judgment and quality and comprehensive,continuous response analysis of test results fluctuation graphics.Combing quality control chart and blank test can not only realize the detection limit of the test,but also control the dynamic of the experiment of all aspects of conditions.The wide use of this method can improve the laboratory analysis testing and quality management level and ensure data quality.
