The features of the atomic-absorption method of measurement, determining the scope of the analyzer “Spectrum” series are considered, the comparative characteristics of facilities and tools of instrumental control are presented. The ideology of the outlining measurement design of atomic absorption device is briefly described. The characteristics of the analyzer toolkit “Spectrum-5-4”, allowing to define the content of more than 60 elements in various media are compared. The important role of developed by the specialists of “Soyuztsvetmetavtomatika” and certified by State Standard of measurement techniques, which are supplied with the instrument and guarantee high accuracy and reproducibility erroneous measurement results is stressed. The comparative specifications of atomic absorption spectrometer “Spectrum-5-4” and spectrometers of world's leading companies, such as contrRAA300 (PerkinElmer Instruments, USA), PinAAcle 900 (Analytik Jena AG, Germany) are given. Ways of further improvement and design features of the analyzer “Spectrum-5-4” which allowed to bring it to the level of the best world standards are described. The most effective ways to use accessories that can be supplied with analyzer series “Spectrum” are considered. For example, adapter RGS 1-1 allows to expand the measurement range for mercury, arsenic and selenium in 1,000 times. Flow measuring hub type BC-01 improves the sensitivity of heavy metals, gold and platinum microcontents detection in 20-30 times. The paper contains specific examples of effective application of the instrument “Spectrum-5-4” for the determination of 30 elements in a variety of products and environments. The possibilities and the comparative characteristics of methods of atomic absorption and X-ray fluorescence are analyzed. The experience of the analyzers application in the Russian and foreign enterprises is reported.
