Analytical chemistry - a science, developing the theoretical foundations of the chemical analysis of substances and materials and develop methods for the identification, detection, separation and determination of chemical elements and their compounds. The qualitative analysis of the problem include:
1) establishing a presence (finding the opening) in a sample of those components (molecules, atoms, ions);
2) identification of substances and components in a sample of unknown composition (the establishment of an appropriate analogy standards) .
Quantitative analysis of the problem - definition of the content or concentration of the components in the sample.
The subject of it as a science - the improvement of existing and development of new methods of analysis, the search for the possibilities of their practical application, the study of the theoretical foundations of analytical methods. Infrared spectroscopy - section spectroscopy studies the interaction of infrared radiation with matter. When the passage of infrared radiation through a substance is excited vibrational motions of molecules or their fragments. At the same time there is a weakening of the light intensity transmitted through the sample.
The extraction-photometric analysis (EPMA) it is hybrid method of analysis, in which combine extraction (as method excretion, separation and concentrating) and spectrophotometry. This method is used in the analysis of complex mixtures when necessary to determine small amounts of certain substances in the presence of large amounts of others, in determining the presence of impurities in the main component, and also in cases where the direct determination of the element of interest in a mixture with great difficulty. In the extraction of small quantities of impurities is not only their separation, but also the concentration. Therefore, the extraction-photometric method is particularly important in connection with the determination of small amounts of impurities in high-purity substances, widely used in the nuclear and semiconductor technology. Extraction-photometric methods of analysis are highly sensitive methods, they are growing rapidly and are very promising.
Physical and chemical methods of analysis based on the dependence of the physical properties of a substance by its nature, an analytical signal is a physical value. properties operably linked to a mass concentration or a defined component.
Physico-chemical analysis methods may include chemical transformations defined compounds, sample dilution, the concentration of analyte, the masking of interfering in-in, and others. In contrast to the "classical" chemical methods of analysis, where the analytical signal is a mass in the islands or the extent to physical and chemical methods of analysis as the analyte. Signal intensity of radiation used, the current strength, electrical conductivity, etc., and a potential difference.
