Atomic Absorption Analysis

Atomic absorption analysis is one of the most common methods for analyzing substances in the laboratory. It is based on measuring absorption spectra and allows one to determine the qualitative and quantitative composition of a substance.

The principle of operation of the method is that a sample of a substance is placed in a special chamber, where it is exposed to ultraviolet radiation. In this case, the atoms of the substance begin to absorb light of a certain wavelength. This leads to a change in the absorption spectrum, which can be measured using a special device - an atomic absorption spectrometer.

Analysis by the atomic absorption method can be both qualitative and quantitative. In the first case, only the presence or absence of a certain element in the sample is measured, and in the second, its concentration is measured.

The use of atomic absorption analysis is widely used in various fields of science and technology. For example, it is used to determine the content of metals in water, soil and other materials, to control the quality of food products, and to analyze the composition of drugs.

However, like any other analysis method, atomic absorption has its limitations. For example, some elements may be difficult to determine due to their high concentrations or low solubility in water. This method can also be expensive and requires a highly skilled operator.

Overall, atomic absorption analysis is an important tool for scientific research and product quality control. It allows you to quickly and accurately determine the composition of a substance and can be used in a wide variety of fields of science and industry.

Atomic Absorption Analysis

Introduction The method is so named because, unlike spectroscopy, it does not require preliminary decomposition of the precipitate in a vacuum. The method is based on measuring the intensity of atomic emission from material atoms (light absorption); An atomic spectrometer is also designed on this principle—exactly so,
