Analytical quality control [An IAEA service]

Journal Article:

Abstract

In analytical chemistry the determination of small or trace amounts of elements or compounds in different types of materials is increasingly important. The results of these findings have a great influence on different fields of science, and on human life. Their reliability, precision and accuracy must, therefore, be checked by analytical quality control measures. The International Atomic Energy Agency (IAEA) set up an Analytical Quality Control Service (AQCS) in 1962 to assist laboratories in Member States in the assessment of their reliability in radionuclide analysis, and in other branches of applied analysis in which radionuclides may be used as analytical implements. For practical reasons, most analytical laboratories are not in a position to check accuracy internally, as frequently resources are available for only one method; standardized sample material, particularly in the case of trace analysis, is not available and can be prepared by the institutes themselves only in exceptional cases; intercomparisons are organized rather seldom and many important types of analysis are so far not covered. AQCS assistance is provided by the shipment to laboratories of standard reference materials containing known quantities of different trace elements or radionuclides, as well as by the organization of analytical intercomparisons in which the  More>>

For practical reasons, most analytical laboratories are not in a position to check accuracy internally, as frequently resources are available for only one method; standardized sample material, particularly in the case of trace analysis, is not available and can be prepared by the institutes themselves only in exceptional cases; intercomparisons are organized rather seldom and many important types of analysis are so far not covered. AQCS assistance is provided by the shipment to laboratories of standard reference materials containing known quantities of different trace elements or radionuclides, as well as by the organization of analytical intercomparisons in which the participating laboratories are provided with aliquots of homogenized material of unknown composition for analysis. In the latter case the laboratories report their data to the Agency's laboratory, which calculates averages and distributions of results and advises each laboratory of its performance relative to all the others. Throughout the years several dozens of intercomparisons have been organized and many thousands of samples provided. The service offered, as a consequence, has grown enormously. The programme for 1973 and 1974, which is currently being distributed to Member States, will contain 31 different types of materials.}
