Every year, plenty of exhibitions and conferences are hold around the world. Some of these are of particular interest to experts in the field of analytical chemistry, since they determine the development direction of the industry. Two such events were held in the spring and summer of 2019 in the United States: the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy and the Annual Conference of the American Society for Mass Spectrometry. Thousands of scientists attended the conferences and followed the programs in Internet broadcasts. The satellite exhibitions of the conferences gathered the leading manufacturers of analytical equipment and materials

EA-IRMS / SIRA Mass Spectrometry of Stable Carbon Isotopes 13C / 12C in Dissolved Carbon Dioxide of Sparkling and Sparkling Pearl Wines DOI: 10.22184/2227-572X.2019.09.4.282.288
A new analytical approach is presented in the study of the composition of stable carbon isotopes 13С / 12С in carbon dioxide dissolved in sparkling and sparkling pearl wines. The new approach is based on a simple and quick way to prepare samples for analysis, which eliminates the use of complex and expensive equipment. The developed approach was first applied to study of the composition of stable carbon isotopes13С / 12С (δ13СVPDB) in wines presented on the Russian market in order to evaluate the nature of dissolved carbon dioxide. The results show that the values of δ13СVPDB of carbon dioxide in analyzed samples of sparkling and sparkling pearl wines range from –30.88 to –25.59‰, and in the carbonated wine drink they reach the level of –42.14‰. The analytical development based on the proposed method for preparing samples for isotopic measurement has shown its effectiveness in conducting research on technogenic factors that have a direct impact on quality, including authenticity of food products. The results of testing the new approach allow recommending it for use in assessing the quality of sparkling and sparkling pearl wines, as well as mineral water and other drinks containing dissolved carbon dioxide.

Qualification of HPLC equipment. Testing of silica-based HILIC and IC columns DOI: 10.22184/2227-572X.2019.09.4.298.301
An original method is proposed for testing polar columns based on silica gel under conditions of ionic, hydrophilic, and mixed ion-hydrophilic HPLC. It allows to evaluate and compare the physicochemical and operational characteristics of the columns: HILIC retention, sign and charge of the ion exchanger (that determine the retention in ion chromatography and the selectivity in mixed IC / HILIC HPLC), chemical inertness of polar silica-based stationary phases and packing efficiency. The conditions under which the proposed test can be successfully applied to qualify chromatographic columns for HILIC and IC HPLC are discussed.

He was considered an unrealized genius. Universal chemist Yu. A. Klyachko DOI: 10.22184/2227-572X.2019.09.4.320.322
In 2020, marks the 110th anniversary of the birth of Yuri Arkadyevich Klyachko (1910–2004), doctor of chemical sciences, professor, Honored Worker of Science and Technology of the RSFSR, a well-known chemist, primarily an analytical chemist. He did a lot to determine gases and non-metallic impurities in metals and alloys, to analyze food products; was one of the few who delved into the so-called general questions of analytical chemistry. But his interests extended to many other areas: he published many works on the structure of metals, on the appearance of hydrogen in the production and processing of aluminum.
