      The kernel density estimate as a measure of the performance of one and two-dimensional TLC systems with large retention datasets in the context of their use in fingerprinting
      L KOMSTA*, K. SZEWCZYK (*Med. Univ. of Lublin, Chair and Dep. of Med. Chem., Fac. of Pharm., Jaczewskiego 4, 20-090 Lublin, Poland)

      Acta Chromatographica 21(1), (2009). Introduction of a new objective chromatographic response function RK, based on the kernel density estimation, for evaluation of the fingerprinting performance of a particular TLC system (uniformity of retention) for which a large set of experimental hRf values of possible components of the mixture is available. The RK criterion is insensitive to large numbers (hundreds or thousands) of hRf values, can be applied to one and two-dimensional TLC and is easily computed.

      Application of TLC for the investigation of separation of some isomeric Naphthalene derivatives
      J.K. ROZYLO*, H. KOLODZIEJCZYK, (*Inst. of Chem., Maria Curie-Sklodowska Univ., 20-031 Lublin, Poland)

      J. Planar Chromatogr. 2, 161-162, (1989). Optimization of a ternary mobile phase utilizing generalized equation. Two less polar solvents were mixed 1:1 and a third, more polar solvent added to the mixture to produce mole fractions between 0.1 and 0.9. Chromatographic parameters evaluated via Rm values. For the separation of 1,4- and 1,5-isomers of naphthalene compounds on silica, carbon tetrachloride - chloroform 1:1 with the addition of 0.5 - 0.7 mole fractions of methanol or acetone were found most suitable.

      Partial correlation coefficients in a study of retention mechanism, RP TLC and RP HPLC
      T. KOWALSKA*, A. PODGORNY, B. WITKOWSKA-KITA, (*Inst. of Chem., Silesian Univ., 9 Szkolna Str., 40-006 Katowice, Poland)

      J. Planar Chromatogr. 5, 192-196 (1992). New means of investigating intermolecular interactions between the components of binary, reverse phase chromatography mobile phases and the solutes being analyzed. A statistics-based approach utilizing partial correlation coefficients was chosen.

      Correlation of retention parameters of pesticides in normal and reversed phase systems
      T. TUZIMSKI, E. SOCZEWINSKI, (Dept. of Inorg. and Anal. Chem., Med. Acad., Staszica 8, 20-081 Lublin, Poland)

      Part IV. (2001) Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 353-354. Determination of relationships between RF values and mobile phase composition for twenty moderately polar pesticides in systems of the type normal- and reversed phase HPLC and TLC. The optimization of the particular separation parameter of HPLC by preliminary experiments with TLC is an obvious step.

      The peculiarities of adsorption–exclusion transition of poly(methyl methacrylate) in binary mobile phases with acetonitrile as displacer
      L. LITVINOVA*, N. BELNIKEVICH (*Institute of Macromolecular Compounds of the Russian Academy of Sciences, Bolshoi pr. 31, 199004 St.-Petersburg, Russia,

      J. Planar Chromatogr. 26, 147-152 (2013). TLC of poly(methylmethacrylate) (PMMA) on silica gel with acetonitrile binary solvent mixtures with carbon tetrachloride, toluene, methylene chloride, chloroform and dichloroethane. Mark-Kuhn-Houwink parameters for PMMAs, Snyder’s parameters and the measured intrinsic viscosity values for PMMA. The characteristics of adsorption-exclusion transition depends both on thermodynamic affinity of the solvent for the polymer and macromolecule-to-pore size ratio.

      Comparison of different TLC techniques as pilot method of mixtures separation by liquid column chromatography
      J.K. ROZYLO, M. JANICKA, (Fac. of Chem., Marie Curie-Skoldowska Univ., 20-031 Lublin, Poland)

      Proc. 6th Int. Symp. Instrum. Planar Chromatogr., (Interlaken 1991), Inst. Chromatogr., Bad Dürkheim, FRG, 321-332 (1991). TLC is used as pilot technique for HPLC of chrysene, dichlorophenoles, nitrophenol, bromonitrobenzenes and nitrotoluene. Mobile phases for both TLC and HPLC were hexane - benzene , hexane - ethylene chloride, hexane - ethyl acetate; for stationary phase silica gel was used. Solute retention (RM) values of TLC are mathematically compared with k’ values of HPLC.

      Comparison of adsorption in liquid-solid chromatography on the basis of different models of retention
      Barbara Oscik-Mendyk (Faculty of Chemistry, M. Curie-Sklodowska University, M. Curie-Sklodowska Sq. 3, 20-031 Lublin, Poland)

      J. Planar Chromatogr. 18, 199-202 (2005). Evaluation of two models of retention in liquid adsorption chromatography. Terms related to adsorption from two equations based on different retention models were compared. The terms were calcutated for selected substances in four chromatographic systems with a different polar modifier. Analysis of the data has proved the comparability of the terms and that they can be used interchangeably to describe adsorption phenomena. TLC of e.g. nitroanilines, nitrotoluidines, nitrophenols on silica gel in horizontal chambers with heptane - ethyl acetate, heptane - 1,4-dioxane, heptane - tetrahydrofuran and heptane - ethylene chloride.
