J. Planar Chromatogr. 28, 133-138 (2015). HPTLC on RP-18W phase with acetonitrile - water 1:3 with acetic buffer (4 mM) and with or without ion-pair reagent (sodium-1-heptane sulfonate, tetrabutylammonium chloride, and bis(2-ethylhexyl)hydrogen phosphate). The influence of the addition of different ion-pair reagents to the mobile phase on the velocity of the electroosmotic flow in pressurized planar electrochromatography was examined. The results demonstrate that in pressurized planar electrochromatography, a small addition of ion-pair reagents affects the selectivity of separation.
Chromatogr. Sci. 55, 43-69 (1991). A review with 33 references. Discussion of physical phenomena important for the chromatographic process, as well as main concepts for efficiency of separation. Also review of semiempirical models of partitions and adsorption chromatography and discussion of their usefulness in every day lab practise.
J. Planar Chromatogr. 7, 63-69 (1994). Investigation of the mechanism of solute retention in silica gel adsorption TLC using three different mobile phases, i.e. isopropanol - hexane, isopropanol - heptane, isopropanol - octane mixtures. The empirical results were compared with predictions based on the classical displacement model, and on the so-called alternative model which concentrates on intermolecular interactions between the components of mixed mobile phases.
Planar Chromatogr. 19, 332-341 (2006). In TLC the development step distributes the sample throughout the layer. The essential reqirement for quantitative TLC is a constant sample distribution in each sample spot. The paper shows that quantitative TLC is possible even if the concentration of the sample is not constant. In the absence of uniform sample distribution classical Kubelka-Munk theory must be extended. The extended theory presented is not only capable of describing asymmetrical scattering in TLC layers but also includes a formula for absorption and fluorescence in diode-array TLC. With this new formula all different formulas for diode-array thin-layer chromatographic evaluation are combined in one expression.
J. Liq. Chromatogr. Relat. Technol. 32, 1317-1330 (2009). New study of relationship between structure and chromatographic behaviour of acylanilide derivatives. TLC of acylanilide derivatives on TLC aluminum foil with acetone - water and methanol - water mixtures. The hRf values related to the molecular lipophilicity and to the specific hydrophobic surface area of the analytes were calculated.
J. Planar Chromatogr. 28, 24-29 (2015). HPTLC of new derivatives of 1,2,4-triazole and thiosemicarbazide on RP-18W with 30 % acetonitrile and 40 % MeOH as organic modifiers, both in water, detection at UV 254 nm. 30 % provided the most close phase ratio in TLC and HPLC. The method can be used as a pilot technique for the anticipation of retention in HPLC.
J. Planar Chromatogr. 29, 281-286 (2016). HPTLC of newly synthesized cycloalkylspiro-5-hydantoins (derivates of 3-(4-substituted benzyl)-cyclopentanespiro-5-hydantoin, 3-(4-substituted benzyl)-cyclohexanespiro-5-hydantoin, and 3-(4-substituted benzyl)-_x000D_cycloheptanespiro-5-hydantoin) on RP-18 with varying content of methanol 50–90%. Multivariate analysis enabled the classification of the lipophilicity and structural properties of the investigated compounds.
various dyes on silica and cellulose stationary phases using a data mining approach
J. AOAC Int. 101, 1437-1447 (2018). Micro-TLC of 18 standard dyes (Amaranth, Bromophenol blue, Bromothymol blue, Patent blue V, p-Xylenol blue, Brilliant Black BN, Erythrosine, Fluorescein, Carmine, Naphthalene black 10B, Phenol red, Bromocresol purple, Sudan II, Sudan III, Sudan IV, Bromocresol green, Dimethyl yellow, and Methyl red) on silica and cellulose with different solvent mixtures (methanol – water and dichloromethane – methanol) in proportions varying from 0 to 100 %. Chromatographic parameters and quantum mechanics properties of each solute were used along with data mining to model the chromatographic behavior.
