Atomic absorption spectrometry (AAS) is an instrumental method for quantitative analysis of the elemental composition of substances, which has become widespread due to its high selectivity and efficiency. The main advantage of AAS is that the sample can be analyzed with minimum preliminary sample preparation and a large number of elements in a wide range of concentrations can be determined. All this makes AAS convenient to use and indispensable in the study of various samples – from high-purity solutions to complex matrices, such as ores, alloys, natural and waste water, soils and feed, and also effective for poorly soluble objects, such as slags, ceramics.
