研究成果: Article査読


Quality control surveys are often planned and implemented to clarify the inter-laboratory analytical errors. However, since it is not clear how the results of surveys should be analyzed, information for improvement is not provided and therefore the surveys just help grasp the situation. The organizer of a survey should not only sum up the results, but extract useful information obtained from the many participating laboratories and tackle the problems for systematic improvement, and make an appropriate evalution of each laboratory and offer useful information making it possible for each laboratory to improve the accuracy and precision. We propose a method to analyze the results of a quality control survey and develop a data analysis system. This method uses an Operation Line, which is estimated from all materials, to evaluate laboratory, as well as examine each material. The method and the system enable us to effectively evaluate the accuracy and precision of each laboratory's measurement.
