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.
Everyday practical tasks require innovative analytical solutions DOI: 10.22184/2227-572X.2019.09.4.258.262
Educational-scientific chemical-analytical laboratory of the Russian State University of Oil and Gas (NRU) named after I. M. Gubkina is one of the leading testing laboratories in the Russian Federation in the declared field of accreditation. For more than twenty years, chemists under the guidance of academician A. G. Dedov successfully solve the most complex practical problems of creating methods for monitoring of the environment, water resources, drugs, the quality of oil products, etc. An important and very popular area of work is the development of express methods and multicomponent test tools for monitoring the quality of fuels and lubricants. The head of the laboratory Alexey Georgievich Dedov and quality manager – Delgir Andreevna Sandzhieva told about the history of the creation of the laboratory, achievements, practical results of work and plans for the future.
The opening of the Helikon Laboratory at Moscow State University is a step towards the integration of modern technologies in education DOI: 10.22184/2227-572X.2019.09.4.264.265
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.

This article is forth one in the series of articles describing a monitoring of hottest fields of chemistry, including analytical chemistry. The monitoring is based on the use of modern scientometric techniques, namely a citation / co-citation statistics of scientific articles. The study focuses on a subject matter of emerging research fronts. This methodology results in the conclusion that in 2018 research fronts in solar energetics, nanotechnologies, and chemical catalysis, were continued. The distinct trend of biologization and miniaturization of chemical analysis was also remained.
