В данном обзоре освещены современные направления применения метода атомно-абсорбционной спектрометрии с источником непрерывного спектра (ААС-ИНС) для количественного анализа. Рассмотрены подходы к анализу образцов различного состава: объектов окружающей среды, пищевых продуктов, растительных и биологических материалов, металлосодержащих образцов, нефти и нефтепродуктов, косметических средств. Приведены методические решения (применение различных модификаторов, оптимизация программ нагрева графитовой печи, проведение предварительного концентрирования) для достижения низких пределов обнаружения и определения. Отмечено различие между одновременным многоэлементным определением и последовательным определением из одной аликвоты. Представлен анализ нормативной базы по действующим стандартам с использованием метода ААС-ИНС и аттестованным методикам, включенным в Федеральный информационный фонд по обеспечению единства измерений. Обзор демонстрирует, что ААС-ИНС с электротермической атомизацией является высокочувствительным, точным и экономически эффективным аналитическим инструментом, и его дальнейшее развитие связано с разработкой многоэлементных методик анализа объектов сложного состава.

 

This review discusses current applications of high-resolution continuum source electrothermal atomic absorption spectrometry (HR-CS ETAAS) for quantitative analysis. Analytical approaches for samples of various compositions are considered, including environmental objects, food products, plant and biological materials, metal-containing samples, crude oil and petroleum products, and cosmetics. The following methodological solutions are presented in order to achieve low detection and determination limits: the use of various modifiers, optimisation of graphite furnace heating programms, preliminary extraction and concentration procedures. The differences between simultaneous multielement determination and sequential determination within a single aliquot are highlighted. An analysis of the regulatory framework is provided, covering current standards for HR-CS ETAAS methods and certified procedures included in the Federal Information Fund for Ensuring the Uniformity of Measurements. The review demonstrates that CS ETAAS is a highly sensitive, accurate, and cost-effective analytical tool, remaining competitive among modern spectrometric techniques and its further development is linked to the expansion of multielement analytical methodologies for complex matrices.
