Origin软件在能力验证数据报告图示制作上的应用
能力验证是对参加实验室检测/校准能力和管理体系运行状况进行客观考核, 促进其能力提升的一种有效手段。目前, 主要采用稳健四分位法对能力验证数据进行统计分析, 运用Excel、MATLAB等软件制作能力验证数据报告图示。Origin是一种公认的简单易学、操作灵活、功能强大的科学绘图与数据分析软件。它基于模板绘图, 软件本身提供了几十种二维和三维绘图模板而且允许用户自己定制模板。Origin的数据分析主要包括统计、信号处理、图像处理、峰值分析和曲线拟合等。本文以“葡萄酒中铜和胭脂红的测定”(CNCA-14-B08)能力验证项目各参加实验室提交的铜含量数据为例, 详细介绍了使用Origin软件制作z比分数柱状图、重复测定结果偏差棒图、检测结果分布频率直方图、z值直方图和尧敦图的方法。
Proficiency testing is an efficient measure of laboratory ability improvement via objective evaluation of the detection/calibration ability and management system running status. Currently, robust quartile method is mainly used for the statistical analysis of proficiency testing data. Meanwhile, Excel and MATLAB software are commonly applied to draw report graphical representation of proficiency testing data. Origin is a scientific drawing and data analysis software, which recognized as an easy learning and flexible operation software with powerful functions. Origin is based on the template drawing, the software itself provides dozens of two-dimensional and three-dimensional drawing templates, and also allows users to customize the template. The date analysis of origin includes various comprehensive mathematical analysis functions, such as statistics, signal processing, image processing, peak analysis and curve fitting, etc. The copper content data of the participator submitted in “Determination of copper and carmine in wine” (CNCA-14-B08) proficiency testing project is used as an example to detailedly describe the plotting of z score histogram, repeat determination results error bar chart, determination results distribution probability histogram and Youden plot via origin software in this article.
