      A new approach to separation number in planar chromatography
      B. KLAMA, T. KOWALSKA*, (Inst. of Chem., Silesian Univ., 9 Szkolna Street, 40-006 Kattowice, Poland)

      J. Planar Chromatogr. 10, 427-433 (1997). A new approach to separation number (SN) in planar chromatography has been derived from a set of physicochemical premises, the most important of which has been experimentally verified. The new model has been used practically to evaluate the efficiency of selected planar chromatography systems in terms of separation number (SN). TLC of naphthalene, phenanthrene, chrysene, pyrene, dibenzyl ether, and 1-naphthol on silica with acetone - hexane and chloroform - hexane binary mixtures in different ratios. Detection under UV.

      Raman spectroscopic quantification of the extent of hydrolytic cleavage of organic ligands from the surface of CN- and DIOL-type stationary phases in TLC with mobile phase buffers of pH from 1 to 10
      G. KOWALIK, B. KLAMA, T. KOWALSKA*, (*Inst. of Chem., Silesian Univ., 9 Szkolna Street, 40-006 Katowice, Poland)

      J. Planar Chromatogr. 13, 290-295 (2000). Investigation of the hydrolytic cleavage of the 3-cyanopropyl and diol ligands from the silica gel matrix surface. Hydrolytic cleavage was induced by use of mobile phases comprising mixtures of methanol, water, and buffers of different pH. CN- and diol-type polar ligands are less susceptible to hydrolytic cleavage than apolar (C 8 and C 18) ligands. The difference can probably be explained by use of an ion-exclusion mechanism.

      Reversed-phase thin-layer chromatography of stereodefined 2-alkylidene-4-oxothiazolidines and 1,2-dithiols
      M. NATIC, R. MARKOVIC, K. ANDELKOVIC, D. MILOJKOVIC-OPSENICA, Z. TESIC* (*Faculty of Chemistry, University of Belgrade, P. O. Box 158, 11001 Belgrade, Serbia and Montenegro)

      J. Planar Chromatogr. 17, 323-327 (2004). TLC of three 1,2-dithioles and five 2-alkylidene-4-oxothiazolidines on RP-18 with binary mixtures of methanol and water, tetrahydrofuran and water, and acetone and water in different proportions. Detection with iodine vapor. Good correlation of chromatographically obtained lipophilicity data with calculated log P values.

      Lipophilicity of natural sweeteners estimated on various oils and fats impregnated thin-layer chromatography plates
      C. SARBU*, R. D. BRICIU (*Babes-Bolyai University, Faculty of Chemistry and Chemical Engineering, Arany Janos Str. No. 11, 400028, Cluj Napoca, Romania; csarbu@chem.ubbcluj.ro)

      J. Liq. Chromatogr. Relat. Technol. 33, 903-921 (2010). A variety of TLC-plates impregnated with oils (paraffin, olive, sunflower, corn, castor, cod liver) and fats (margarine butter, pig, sheep, pullet, human) were indirectly evaluated regarding lipophilicity by employing a series of experimental parameters estimated for a representative group of natural sweeteners from retention data. TLC of 13 sugars on oil- and fat-impregnated silica gel layers using five organic solvents as organic modifiers. Best results were obtained with mixtures of acetonitrile and water with chamber saturation for 10 min. Detection of the sugars by treatment with silver nitrate and sodium hydroxide followed by heating at 105 °C for 5 min.

      Analysis of chromatographic parameters in the systems with ternary mobile phases
      B. OSCIK-MENDYK, J.K. ROZYLO, (Inst. Chem., M. Curie-Sklodowska Univ., Lublin, Poland)

      J. Liquid Chrom. 10, 1399-1415 (1987). Proposition of a new method for the analysis of chromatographic parameters (optimal choosing of the mobile phase composition) obtained for ternary mobile phases. Investigation were carried out for 6 model substances (naphthalene, o-nitrotoluene, o-bromonitrobenzene, o-nitroaniline, o-nitrophenol, fluorenone) with single-, two- and three component solvent systems in various concentrations.

      An optimization function and its application to the multidimensional thin-layer chromatography of protein amino acids
      A.G. HOWARD, I.A. BOENICKA, (Dep. Chem., Univ. Southampton, Southampton, UK S09 3NH)

      Anal. Chim. Acta 223, 411-418 (1989). Optimization of multicomponent mobile phase system in TLC by using an overall figure of merit (FOM) for separation, based on an equation which defines the extent of the separation of pairs of spots. Demonstration of the method in simplex optimization of separation of 17 amino acids by two-dimensional TLC on cellulose with tert butanol – 25% NH3 – MEK – water 12:6:1.52:2.48 for the first dimension, and butanol – acetone – acetic acid – water 10.29:6.82:5.06:3.65 for the second.

      Determination of the surface irregularity of TLC and HPTLC plates
      T. CSERHATI*, A. SOMOGYI, (Central Res. Inst. for Chem., Hungarian Acad. of Sci., H-1525 Budapest, POB 17, Hungary)

      J. Planar Chromatogr. 5, 319-322 (1992). Check of 9 different types of TLC and HPTLC plates for surface irregularities with a TLC scanner operating in the wavelength range 200-700 nm. The data matrix was evaluated by principle component analysis and by spectral mapping. Most irregularities were found between 200-300 nm; in the visible region the surfaces seemed more even. The HPTLC plate showed the smallest irregularities.

      Physico-chemical modeling of solute retention in reversed phase liquid chromatography with acetonitrile - phosphate buffer eluents
      A. PODGORNY, T. KOWALSKA*, (Inst. of Chem., Silesian Univ., 9 Szkolna Street, 40-006 Katowice, Poland)

      J. Planar Chromatogr. 7, 291-293 (1994). The new retention model originally developed for reverse phase liquid chromatographic systems employing acetonitrile - water mobile phases has been adapted for description of solute retention in analogous systems using acetonitrile - phosphate buffer mixtures. The basic physical relationships of this approach have been experimentally tested, and excellent agreement found between theory and practice of the phenomenon considered.
