Laboratory Equipment: Biological Safety Cabinet, Fume Hood or Laminar Flow Cabinet? 10.22184/2227-572X.2026.16.4.246.251
Laboratory safety was once limited to removing toxic vapours from the laboratory. Today, it also requires the control of submicron particles and the isolation of the working environment. The nature of laboratory hazards has become more complex, while the requirements for working conditions have become more stringent. In laboratory practice, three types of equipment are used: laminar flow cabinets, chemical fume hoods, and biological safety cabinets. Each serves a specific purpose and reflects a particular stage in the development of laboratory protection systems.

Direct Determination of Silver in Complex Matrix Samples by Synchrotron Radiation X-ray Fluorescence Analysis 10.22184/2227-572X.2026.16.4.296.301
The paper presents the evaluation of instrumental conditions (excitation quantum energy) and the analytical range for silver determination in complex geological matrices using synchrotron radiation X-ray fluorescence analysis (SR-XRF) without chemical sample preparation by reducing the detection limit to the lower bound of ore-grade concentrations. The study investigated certified reference materials (CRMs) of black shales (SCHS‑1 and SLg‑1), loose sediments (SGHM‑3 and SGHM‑4), and copper-nickel sulfide ore (VT‑1). Silver determination was performed on pressed powder pellets of the CRMs with an average mass of 22,9±0,7 mg and a density of 0,4 g/cm3 using both external calibration and direct external standard methods. SR-XRF analysis of the samples at an excitation energy of 30 keV yielded fluorescence spectra for the specified CRMs, exhibiting peaks corresponding to the Kα1,2 and Kβ1–3 lines of Ag at 22,16; 21,99; 24,94; 25,46 and 24,91 keV, respectively, with the latter detected at concentrations of 34 mg/kg. The limit of detection for silver was 0,5 and 1,7 mg/kg for the direct external standard method and 1,4 mg/kg for the external calibration method. While both methods offer comparable accuracy for silver determination in silicate and anthropogenic matrices, the calibration method is more versatile, robust against matrix effects, and comprehensively accounts for instrumental errors as well as instrumental and background fluctuations.

Instrumental Neutron Activation Analysis: Current Status and Future Prospects 10.22184/2227-572X.2026.16.4.252.262
The capabilities of instrumental neutron activation analysis (INAA) for the investigation of mineral raw materials, technogenic materials, and environmental objects are reviewed. The principles of the method, as well as its advantages and limitations in the determination of trace elements in complex mineral and carbonaceous matrices, are discussed. A review of published studies on the application of INAA to the analysis of coal, coal combustion products, ores, and environmental samples is presented. INAA is shown to be a highly sensitive multi-element analytical technique suitable for the determination of rare, rare-earth, critical, toxic, and radioactive elements over a wide concentration range with minimal sample preparation. The prospects of applying INAA for analytical control of mineral resources and environmental monitoring are highlighted

Russian ECOVIEW Spectrophotometers. Solutions for Laboratory Digitalization 10.22184/2227-572X.2026.16.4.264.267
Russian laboratories are evolving and changing in line with the demands of the times. Today, analytical equipment is no longer simply required to deliver accurate measurements. Traceability of results, user activity monitoring, data security, and integration with information systems are increasingly important. Overall, laboratories must comply with industry standards, including GOST 17025-2019 and GMP. This is precisely the direction the ECOVIEW series of spectrophotometers, manufactured in Russia at the Pskov Ecology production facility in Pskov, is heading. Today, ECOVIEW offers a wide range of photometric equipment: from affordable devices for routine measurements to professional scanning systems with a built-in computer, event log, and the ability to integrate into a laboratory’s digital infrastructure. This article discusses the capabilities and advantages of new Russian-made spectrophotometer models.

Exhibits from the Virtual Chemistry Museum Collection. A New Popular Library of Chemical Elements. Beryllium: Precious and Deadly
10.22184/2227-572X.2026.16.4.302.306
We continue publishing materials created by the Virtual Chemistry Museum project, led by its editor-in-chief, Alexey Sergeyevich Paevsky. The idea for the Virtual Chemistry Museum originated at the N. S. Kurnakov Institute of General and Inorganic Chemistry of the Russian Academy of Sciences and was implemented in the winter of 2023–2024. The platform has been created to accumulate materials on the history of chemistry and interesting facts about its prominent figures, as well as stories about the most important, useful, and unusual substances, materials, and, of course, chemical elements. For the third year, the museum has been developing thanks to grant support from the Russian Ministry of Education and Science as part of the federal project Popularization of Science and Technology and is one of the projects of the Decade of Science and Technology. Readers are invited to explore a story about one element from the ever-expanding interactive Periodic Table of D. I. Mendeleev in the museum’s New Popular Library of Chemical Elements section.
