Features of Determining Organoelement Compounds in Environmental Objects and Biological Media 10.22184/2227-572X.2024.14.6.480.487
In comparison with traditional approaches used in measuring inorganic or organic substances, determining organoelement compounds has its own specifics. First of all, this applies to the use of modern, so-called hybrid methods that combine chromatographic separation and spectral registration of analytes. This publication is devoted to the features of using these methods using the example of measuring the content of the most important groups of organoelement compounds in environmental objects and some biological matrices. The paper provides examples of using a combination of chromatography with mass spectrometry to determine organomercury and organoarsenic compounds. Measuring the content of organotin compounds is considered in more detail. Data on the reference method for measuring the content of organotin compounds in soils and bottom sediments developed at VNIIM, the results of its testing on real objects and certified materials are presented.

Proficiency Testing as a Tool for Confirming the Validation / Verification of Measurement Methods 10.22184/2227-572X.2024.14.6.492.496
A number of generally accepted approaches and algorithms used by laboratories to improve, maintain and demonstrate the reliability and quality assurance of measurement results are considered. Using the example of the procedure for external quality control of laboratory results in the form of participation in proficiency testing programs or interlaboratory experiments, an approach is demonstrated that fully ensures the reliability of results, including when implementing a method (technique). The most complete analysis of reports on the results of participation in proficiency testing programs or interlaboratory comparisons allows one to evaluate the effectiveness of the laboratory.

Instrumental Solutions for Elemental Analysis Based on Plasma Spectrometry 10.22184/2227-572X.2024.14.6.458.464
Elemental analysis is in demand in almost all industries: metallurgy, ecology, agriculture, pharmaceuticals, forensics, chemistry, microelectronics, oil and food industries, aircraft materials production, etc. Among other analytical methods, inductively coupled plasma spectrometry (ICP) occupies a significant place. The article discusses the features of methods of mass spectrometry and optical emission spectrometry with inductively coupled plasma. Both methods effectively complement each other. The capabilities, advantages and technical characteristics of the advanced models of ICP-MS spectrometers (SUPEC 7000) and ICP-AES (EXPEC 6500) are described in detail.

Gas Analysis Methods. What Can an Electronic Nose Do? 10.22184/2227-572X.2024.14.6.476.479
The current level of technological development, the desire for safety and comfort in everyday life have led humanity to the widespread use of various sensors that monitor the parameters of the space around us. One of the key areas in the field of control is the analysis of volatile compounds. Traditional analytical tools are various analyzers for determining the qualitative or quantitative composition of gas mixtures (gas analyzers). The use of gas chromatography-mass spectrometry allows you to determine the molecular weight, elemental composition and molecular structure of compounds present in the sample. These methods require a complex and expensive sampling system for analysis in laboratory conditions. Today, the electronic nose technology is actively developing. What are its features and capabilities? What is fundamentally new in it compared to classical methods? Will it become a replacement or addition to traditional tools, what problems can it solve?

We continue our series of publications dedicated to equipping laboratories with equipment for safe and efficient work with any chemicals. Many microbiological and research laboratories have strict requirements: sterile conditions, no environmental impact on samples and reagents. Laminar shelters and boxes are used to minimize the impact of the external environment and ensure safe working conditions for laboratory technicians. Various protection classes and areas of application of laminar boxes are considered in order to select the right model for specific tasks.

M. S. Schreiber – the First Woman in the World to Make a Discovery in Chromatography. On the 120th anniversary of her birth 10.22184/2227-572X.2024.14.6.498.504
In September of this year, the 120th anniversary of the birth of Maria Semenovna Schreiber, co-author of the outstanding physicist-chemist Nikolai Arkadievich Izmailov on the famous article of 1938, from which the history of thin-layer chromatography is started. The biography and heritage of N. A. Izmailov have been studied quite deeply, unlike M. S. Schreiber. Little is known about her, besides the fact that she did her scientific work in chromatography when she was a graduate student and worked under the supervision of N. A. Izmailov. Meanwhile, Maria Semenovna Schreiber (1904–1992) is the world's first woman to make a discovery in chromatography. In 1938, N. A. Izmailov and M. S. Schreiber came up with a new chromatography method, which was later called thin-layer chromatography (TLC). The article presents for the first time* a biography of Schreiber, as well as some of the events and people that may have served as the source of the two scientists' interest in chromatography.
