Use of Surface-Porous HPLC Columns for Routine Analyzes on Standard HPLC Equipment DOI: 10.22184/2227-572X.2021.11.1.24.28
The article demonstrates the practical possibility of the successful use of surface-porous phases for performing routine analyzes on standard HPLC equipment using a standard injection volume of 20 μL and a pressure of 400 and 600 bar, respectively. Under these conditions, for 2.7 μm surface-porous adsorbents, a specific efficiency of the order of 200-220 thousand tons / m was achieved. The results are illustrated with real examples of HPLC separations from the methods developed by the specialists of the IP company Sychev KS / I.B.S.

Investigation of Tritium in Structural and Functional Materials by Radioluminography Method DOI: 10.22184/2227-572X.2021.11.1.40.44
Most methods of hydrogen isotopes analysis in construction and functional materials only enable to form an opinion about integral quantities of their concentrations failing to provide information about hydrogen distribution in the sample. A new highly-informative analysis technique such as radioluminography allows estimating, to a high precision, the content and distribution of tritium in different materials. It’s a new possibility for investigations of hydrogen interaction with the construction and functional materials. Radioluminography technique enables to deteсt tritium diffusion coefficient over a wide temperature range, even where the application of membrane methods is difficult. The use of various types of IP plates allows detecting tritium as to beta-radiation and X-ray bremsstrahlung. The paper provides examples of the application of the radioluminography method for the qualitative and quantitative determination of tritium on the surface and in the near-surface region of the sample.

Boron Analysis in Glass Powder Using Wavelength Dispersive X-ray Fluorescence Spectrometer DOI: 10.22184/2227-572X.2021.11.1.46.48
The results of the quantitative determination of boron oxide content in glass by the XRF method on a ZSX Primus IV spectrometer using a 4 kW X-ray tube and a modern synthetic multilayer crystal analyzer RX85 are presented. An experimental check of the automatic pressure control system for maintaining a stable vacuum in the measuring chamber has been carried out. The influence of this parameter on the stability of the results obtained is shown. Repeatability tests have confirmed the quality of the results obtained.
