The Metamorphosis of Analytical Chemistry Defining analytical chemistry as the measurement of isolated compositional features in a selected study object ignores the unique perspective that analytical chemists bring to twenty-first century science and society. In this feature article, we will discuss some of the existing preconceptions and misinterpretations of analytical chemistry that occur at present and will tackle them from the more up-to-date perspective of science in the Big Data Era. This will place their influence in context while simultaneously enlarging the scope of the discipline analytical chemistry to its well-deserved prevalent position in present-day science and technology

Fiber Optic Sensors Based on Especially Pure Chalcogenide Glasses The paper presents experimental results on the development of fiber sensors based on passive and active optical fibers made of especially pure chalcogenide glasses for studyingthe chemical composition of liquids by evanescence IR spectroscopy. Spontaneous emission sources of the 1–9 μm spectral range based on REE doped chalcogenide glass fibers with high emission properties were manufactured. On the basis of passive chalcogenidefibers, novel types of high sensitive fiber sensor elements have been developed and created. Various chalcogenide fibers have been successfully tested for the analysis of petroleum
products and environmental objects.

Quality Standard for Routine HPLC Techniques The main factors constraining the growth of the high performance liquid chromatography (HPLC) market are discussed: low economic efficiency of HPLC methods and the absence of an industry quality standard. The characteristics of a qualitative HPLC method are described in detail: correctness, specificity, robustness, sensitivity, as well as economic efficiency. A list of six basic requirements for modern routine HPLC methods, which can form the basis of the standard, is presented and discussed in detail. Several application examples are provided to demonstrate the basic principles. The negative impact of information chaos was noted, when both new and outdated products are advertised, the advertising itself is not always fair, and companies often contradict each other.

The Project of the Department of Chemistry of Lomonosov Moscow State University and the Polytechnical Museum. Chromatography: a Historical Excursus During some years the students of Chemical Department of Lomonosov Moscow State University have been participating in a joint project with the Moscow Polytechnical Museum which is dedicated to the attribution of artifacts of this scientific and enlightenment institution. This article is devoted to historical investigation of appearance of industrial automatic gas chromatograph KHPA‑2 in the domestic market of analytical equipment and to the problem of its maintenance. It is preceded by a historical essay on the history of origin of the chromatographic method of analysis and its variation – gas chromatography. This essay was written on the basis of an analysis of a number of recent Western publications in this area. The article content has been previously presented at student scientific conference On the history of chemical instrumentation and industrial processes, organized by Chemical Department of Moscow State University and Moscow Polytechnical Museum in December, 2019.
