Capillary thin-layer chromatography of antibacterial nitrofuran derivatives
Autor: E. N. Evtyugina, L. A. Onuchak, V. G. Berezkin
Publikováno v: Russian Journal of Applied Chemistry. 82:312-316
A new version of thin-layer chromatography, capillary thin-layer chromatography, which is similar to traditional planar chromatography in the idea of detection of sorbate bands and to high-performance column chromatography in the implementation of th

New thin layer chromatography technique using a gas stream above the plate sorption layer
Autor: K. V. Sednev, V. G. Berezkin
Publikováno v: Doklady Chemistry. 419:65-68
Thin layer chromatography (TLC) is the simplest and a rather efficient version of liquid chromatography and is widely used in analytical practice. In Russia, thin layer chromatography is used in more than 10000 laboratories. Therefore, further develo

On the application of thin-layer chromatography in petroleum chemistry
Autor: V. G. Berezkin
Publikováno v: Petroleum Chemistry. 47:415-420
A possibility for a wider use of thin-layer chromatography in petroleum chemistry is shown. New approach to the derivation of the equation for the retention factor k used for describing the retention in liquid column chromatography is considered. To

Relative Retention in TLC r ij Using Column Liquid Chromatography Terms
Autor: V. G. Berezkin
Publikováno v: Journal of Liquid Chromatography & Related Technologies. 29:2271-2275
Using new approaches for conversion of TLC retention data in terms of column liquid chromatography (CLC), a new term of relative retention r ij for TLC is proposed: The new relative retention term r ij can be used in TLC as a chromatographic constant

Generating gas flows with a constant trace concentration of hydrogen sulfide
Autor: Platonov Igor A, S. Yu. Kudryashov, D. R. Ismagilov, L. A. Onuchak, V. G. Berezkin, I. N. Smygina
Publikováno v: Journal of Analytical Chemistry. 61:52-57
The dynamic gas extraction of hydrogen sulfide from aqueous solutions of sodium sulfide was studied theoretically and experimentally. The effects of the number of bubblers, the concentration of sodium sulfide, and the pH of solution on the concentrat

Relationship between Physicochemical Properties and Chromatographic Retention of Some Adamantane Derivatives
Autor: Svetlana V. Kurbatova, V. G. Berezkin, E. E. Finkel'shtein, K. K. Konstantinova
Publikováno v: Russian Journal of Applied Chemistry. 78:1498-1502
Correlations between physicochemical properties and chromatographic retention parameters of adamantane derivatives were studied. The Kovats indices and contributions of hydrocarbon radicals and functional groups to the chromatographic retention were
