Examination of the effect of facial-meridional geometrical isomerism of metal complexes on their chromatographic behavior, finding meridional corresponding facial ones. Discussion of some possible separation mechanism.

J. Planar Chromatogr. 13, 231-234 (2000). RPHPTLC on RP 18 with methanol - water mixtures. The concentration of methanol in the mobile phase ranged from 50 to 90 % in steps of 10 %. Visualization under UV.

Acta Chromatographica 14, 16-36 (2004). Study on co-elution by using two binary mixtures which can form mixed associative structures by hydrogen bonding: 1) a carboxylic acid (2-phenylbutyric acid) and a ketone (benzophenone), and 2) an aliphatic alcohol (5-phenylpentanol, and the same ketone (benzophenone). By using mild chromatographic conditions and working in the non-linear region of the adsorption isotherm, the co-elution of the two analytes from each pair in the form of a single chromatographic band was demonstrated, three different physicochemical explanations of their densitometrically measured concentration profiles were suggested, and semi-quantitative simulations of these profiles were performed. Discussion and comparison of the experimental results obtained by planar chromatography and HPLC using fully analogous working conditions.

J. Planar Chromatogr. 18, 212-216 (2005). Retention factors on RP-18 layers corresponding to zero percent organic modifier in the aqueous mobile phase were determined for five mobile phase mixtures: methanol - water, acetone - water, acetonitrile - water, 2-propanol - water, and tetrahydrofuran - water and relationships between the retention factors obtained with different organic mobile phase modifiers were examined. A variety of partition coefficients were calculated by use of different software products and the correlation between these partition coefficients and chromatographically obtained lipophilicity was analyzed. On the basis of of correlations between retention factors and the partition coefficient log P, RP-18 with methanol - water as mobile phase was selected as the best RP-HPTLC system for determination of the octanol/water partition coefficient and thus the lipophilicity of the molecules. Visualization under UV light at 254 nm.

J. Chromatogr. B 846 (1-2), 334-340 (2007). Salting-out TLC of sulphonamides on silica gel with aqueous solutions of salts (sulphates, chlorides, nitrates, phosphates, acetates, and thiocyanates) showed that the applied salts have different effects on the retention of sulphonamides according to Hofmeister's classification (e.g. kosmotropes, chaotropes and neutral). Parameters of the linear regression analysis were compared with QSAR data of dependences between the RM values and salt concentration. Chromatographic data obtained by salting-out TLC showed not only the physico-chemical properties of the examined compounds but also information about their activity. The method was suitable for prediction and classification of sulphonamide drugs by localization of other structurally similar compounds with antagonistic activity towards sulphonamides.

J. Liq. Chromatogr. Relat. Technol. 36, 2363-2377 (2013). The impact of substituent of benzanilide moiety on retention of 14 (alkoxy-phenyl)benzamides was assessed by TLC on silica gel and aluminium oxide with various mixtures of n-pentane, benzene and acetone. The TLC method allowed for quantitative structure relationship (QSRR) studies with benzanilide derivatives.

HPTLC of 15 polyoxygenated steroids on unmodified silica gel with non-aqueous binary solvent systems containing acetone – n-hexane or acetonitrile – dichloromethane. Lipophilicity parameters obtained by normal phase chromatography were validated in relation to corresponding reverse phase chromatographic data.
