In 2024, the implementation of the Program for Updating the Instrumentation Base in Russian Scientific Institutes and Universities within the framework of the national project Science and Universities was completed. Since 2019, the Institute of General and Inorganic Chemistry has acquired modern scientific equipment worth more than 500 million rubles. The possibilities and prospects for using this equipment in scientific and applied research are in our report today.

Water is a vital resource for industrial enterprises, many of which implement water-intensive technologies. To carry out analytical control of water quality, the user does not need large expenses. Measuring technologies from the Christmas group of companies, representing ready-made instrumental solutions based on the use of portable equipment, allow a significant reduction in the costs of analytical water control. The presented measuring technologies are characterized by a high level of unification and standardization with typical methods and techniques of water analysis. A variety of portable water control equipment has been developed and is available for supply, including ready-to-use reagents and solutions, sets of dishes, accessories and other equipment, including the necessary water control devices and replenishment kits for consumables.

Over the last 20 years, liquid chromatography has become one of the most used methods for the investigation of natural and synthetic colorants in various objects. It is very important to control the content of azo dyes, based on phenanthrenequinone and hydrazine derivatives, which can potentially have a negative impact on human health. This article is devoted to the possibility of chromatographic separation of some azo dyes based on carbo- and heterocyclic alpha-dicarbonyl compounds. Optimal conditions for the analysis (solvents, eluent and its flow rate, temperature, wavelength) are selected; detection limits and linear ranges of determination of the studied compounds are established.

The Colloidal Electrochemical Laboratory (LACE), from which the Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences grew, was organized by academician Vladimir Alexandrovich Kistyakovsky in Leningrad in 1929. When preparing the material, the author studied the published documents of the Presidium of the USSR Academy of Sciences from the Russian State Library and documents from the Archive of the Russian Academy of Sciences.
