Ecological Systems and Devices Annotation << Back THE PROCEDURE FOR SAMPLING ATMOSPHERIC AIR IN THE QUALITY MANAGEMENT SYSTEM OF AN ACCREDITED LABORATORY N.N. Roeva, S.S. Voronich, D.A. Zaytsev, A.G. Khlopaev, Yu.S. Shadskaya Sampling is the most important stage of quantitative chemical analysis, the final result of determining any component of the natural environment depends on the correctness of the procedure. The article presents one of the main procedures of the quality management system of the analytical laboratory, which establishes safety procedures for sampling atmospheric air, sampling modes, requirements for sampling equipment, sampling conditions and their subsequent storage, the choice of the location of sampling points during fake observations, observations of vehicle emissions, the level of air pollution in industrial areas, determination, as well as documentation of the process. All stages of the procedure are described on the basis of existing regulatory documents and can be recommended for use in any center engaged in quantitative chemical analysis of environmental objects.
