质量控制图在大米镉含量检测中的应用

Application of Quality Control Chart to Cadmium in Rice

质量控制图是实验室分析工作质量水平的直接呈现,想要保证分析结果的可靠性,对实验室进行质量控制是必不可少的。而控制质量的一个重要手段便是绘制质量控制图,通过对所得数据的分析研究,确定质控范围。为确保分析结果的精密准确性和有效性,需要减少自身因素对绘制过程的影响,对实验中的误差进行控制,最终让质量控制图充分发挥其根本性作用。

The quality control chart is a direct representation of the quality level of the laboratory analysis work.To ensure the reliability of the analysis results,the quality control of the laboratory is essential.And an important means of quality control is to draw a quality control chart,the quality control scope could be determined by analyzing the datas.In order to ensure the accuracy and effectiveness of the analysis results,it is necessary to reduce the influence of its own factors on the drawing process,control the error in the experiment,and finally let the quality control chart give full play its fundamental role.
