За прошедшие три постпандемийных года, а также спустя два года после введения санкций против России и активной реализации программы импортозамещения, российский рынок аналитического оборудования сильно изменился – с уходом европейских брендов и производителей из США появились как новые отечественные компании, так и малоизвестные до этих пор производители из дружественных РФ стран. Посетив на выставке «Аналитика Экспо» стенды многих из них, предлагаем читателям краткий обзор продукции, которая стала доступна в России не благодаря, а вопреки.

The use of portable, ready-to-use equipment produced by the Christmas group of companies is one of the promising areas for ensuring water quality control, the need for which is great in various sectors of the economy. The experience of 30 years of work of the Christmas Group in the development of equipment for chemical control allows us to present a wide range of mass-produced complex equipment for chemical analysis, which allows us to consider the proposed water control technologies as unified and in demand in modern conditions. The advantages of application and compliance of ready-made solutions of JSC Christmas+ with regulatory indicators are discussed.

The article describes the process of forming a functional model of a converter capable of measuring the dew point temperature of water in natural gas in the range from +20 to –60 °C. The blocks and subsystems of the functional model are defined that provide the functions of data collection and processing, data storage and distribution in a permanent storage device of an electronic board, the formation of a calibration table, the conversion of the desired value according to the calibration characteristic into a DC output electrical signal. A theoretical (virtual) model has been prepared for further work on the implementation of the concept of a dew point temperature converter on a domestic element base.

The meeting about use of Tsvet's chromatographic method in chemical analysis was convened in 1953 by the Institute of Geochemistry and Analytical Chemistry named after V. I. Vernadsky Academy of Sciences of the USSR (GEOKHI) in commemoration of the 50th anniversary of the publication of M. S. Tswet of the first work on chromatography. Thus, this was the first large-scale event of the Comission of the USSR Academy of Sciences on chromatography – more than 500 people from 39 cities of the USSR gathered, 56 reports were made. Many of the tasks set by the meeting for solving in subsequent years are relevant today.
