The Use of Matrix Reference Materials in Environmental Analytical ProcessesM. Parkany, Aleš Fajgelj Reference materials are needed to enable laboratories to perform comparable tests and analyses. The role of matrix reference materials is not always clear, with confusion arising over nomenclature where the same or similar terms are used for different types of calibration standards, reference materials and internal control samples. Thus competent and conscientious laboratories can arrive at different test results because of their differing uses of environmental matrix reference materials. There is therefore a need to produce clear guidelines. Use of Matrix Reference Materials in Environmental Analytical Processes provides worked examples of how to properly apply the selected reference materials in an analytical process, including method validation, quality assurance and quality control. Quantification of uncertainty is also discussed. The reference materials covered include those certified for trace elements and/or radionuclides and organic microconstituents. Presenting the latest knowledge from leading experts in the field, this unique book will prove an invaluable reference for all those using these materials in their daily work and is aimed at building up their awareness of how reference materials should be utilised. |
