Chromatography-mass spectrometry is an analytical method based on a combination of the capabilities of chromatography for the separation of substances and mass spectrometry, which uses their spectral characteristics for the qualitative and quantitative determination of individual components in complex mixtures. A brief historical background on the development of mass spectrometry, the types of main components of the mass spectrometer and a description of the operation of the chromatographymass spectrometer using the example of the Kristallux‑4000M-Maestro-αMS device, as well as its technical characteristics are provided. The applications of the gas chromatography-mass spectrometer and some specific measurement techniques are listed.

Chlorogenic and caffeic acids are among the most common hydroxycinnamic acids. They are present in a variety of plants, including coffee, tea, and fruits. These compounds are the object of active research with a focus on their biological activity and potential applications in maintenance of human health. This review discusses the importance of caffeic and chlorogenic acids, their applications, and the methods of determination in various objects. The article focuses on the sources of these acids, their biological activity, and their impact on human health. It also discusses modern approaches to the analysis of the content of caffeic and chlorogenic acids in food products, beverages and medicines.

This publication is a brief review of the problem of micro- (MP) and nanoplastics (NP), small polymer particles that pollute the environment and threaten to ecosystems and human health. Characteristics of MF and NP, sources of their enter into the environment, impact on living organisms are considered. Different areas of MF and NP study are highlighted. With the abundance of works carried out, their fragmentation is observed, and there is no whole understanding of threats to human health.

This year marks the 90th anniversary of the birth of an outstanding world-famous scientist, an organizer of science who created the most powerful chromatographic school in our country, as well as a popularizer of chromatography, a science to which Mark Solomonovich Vigdergauz devoted his entire life. Scientific interests of M. S. Vigdergauz covers all areas of chromatography: from the theory and practice of gas chromatography to the development of chromatographic processes using non-ideal eluents, stationary phases and transclassification variants of chromatography based on the use of phase transitions in the stationary and mobile phases. Mark Solomonovich actively introduced gasliquid (GLC) and capillary chromatography into analytical control, developed the use of gas chromatography in non-analytical control and in industrial processes. Under his leadership, one of the first computer data banks of chromatographic retention values of more than twenty thousand organic substances was created, and a minimum set of preferred stationary phases was proposed, taking into account conditional chromatographic polarity. M. S. Vigdergauz proposed the double internal standard method and other methods for calculating chromatograms. The scientist’s research made a significant contribution to the development of gas chromatographic methods for the analysis of oil and petroleum products.
