Securing trust in the quality of results of chemical methods examination

Abstract

Securing trust in the quality of examination results is one of the most important segments of the quality management system. Quality management is the first step in ensuring the quality of analytical procedures and predicts the application of appropriate techniques and procedures in order to fulfill the defined quality requirements with an aim to prevent errors in working process. Activities related to quality management include measures that provide statistical control of accuracy of the examined procedure. These activities describe measures that are used to achieve repeatable and reliable examined results. In order to achieve the maximum reliability of the examined results, the validity of the conducted examination is controlled from entering the sample in the laboratory until the release of reports of examination, by continuously monitoring and following all the activities of the analytical process, as well as complete documentation of the quality management system. By continuously monitoring the quality of examination results and with continuous improvement of its' own work procedures through finding mistakes, analyzing the causes of nonconformity, taking preventive and corrective measures, developing its' own procedures of internal control methods, participating in laboratory comparisons and education of staff, the laboratory provides trust in the quality of examination results, and therefore its' own competence.
