Thermogravimetry for studying the distribution of different TLC impregnating reagents, such as paraffin oil, n-octanol, a quaternary ammonium compound (tricaprylmethylammonium chloride, TCMA), ethylenediaminetetraacetic acid (EDTA), and boric acid on silica gel layers.

J. Chromatogr. A 1183 (1-2), 179-185 (2008). Ultrathin layer chromatography (UTLC) with a 10 µm thick monolithic silica sorbent layer provides fast separations with low limits of detection and reduced analyte and solvent volumes. Production of UTLC plates with controllable nanostructure and thickness. The separation characteristics of the layer depend on the nanostructure of the film. Layers made with in-plane anisotropic nanostructures exhibit a decoupling effect, where the analyte spots do not develop in the same direction as the solvent front moves. Discussion of the possibility of application in multi-dimensional TLC by added layer morphology and material selection.

Presentation of theoretical backgrounds, development, examples of separations, constructional details and principle of action of devices of pressurized planar electrochromatography (PPEC). Description of the development mode in respect of operating variables (composition of the mobile phase, pressure exerted on adsorbent layer, mobile phase flow velocity, temperature of separating system, etc.) influencing separation efficiency (kinetic performance, repeatability, separation time), and the advantages of PPEC such as high kinetic performance, short separation time and different separation selectivities, especially relative to conventional TLC, and its challenge as well.

J. Chromatogr. A 1534, 179-187 (2018). Investigation of the influence of pH of the mobile phase buffer on retention of peptides in both normal phase (NP) and reversed phase (RP) HPTLC systems with C18 silica-based adsorbent as the solid phase. Comparison of the influence of pH on retention and/or migration distance of peptides in separation systems of HPTLC and pressurized planar electrochromatography (PPEC) techniques. It was found that the change of pH of the mobile phase buffer can be used for two-dimensional HPTLC separation of peptides, but much stronger change of separation selectivity can be achieved by overall inversion of separation system type (NP/RP). Influence of the mobile phase pH on selectivity of peptide separation in PPEC is different than that in HPTLC, due to the significant share of electrophoretic effect in mechanism of separation and better selectivity of separation by PPEC, however the change of pH affects the efficiency of the separation system in both techniques, so it can be used for optimization of separation conditions. Discussion of some modifications of PPEC equipment and materials useful for application of this technique in the field of peptide analysis.
