Examination of the retention behavior of positional isomers and polyaromatic hydrocarbons on mixed silica - magnesia layers with various binary eluents. Investigation of the influence of magnesia content in mixed adsorbents and concentration of polar modifier in the eluent on retention.

      Comparison of the retention of phenols, aniline derivatives, and quinoline bases in normal-phase TLC with binary isoeluotropic eluents
      M. WAKSMUNDZKA-HAJNOS *, A. HAWRYL, (Dept. of Inorg. and Anal. Chem., Med. Acad., Staszica 6, 20-081 Lublin, Poland)

      J. Planar Chromatogr. 11, 283-294 (1998). Examination of the retention of different groups of model substances - 16 phenols, 12 amines, 6 quinoline bases - on polar adsorbents - silica gel, alumina, and Florisil - developed with isoeluotropic eluents. The DRM (Dlogk, selectivity) parameters for different substituents of the compounds were compared as parameters of the energies of adsorption of the various chromatographic systems. The DRM values for substituents were correlated with their reactivity constants.

      Separation of strength and selectivity of mobile phase by spectral mapping technique
      E. FORGACS, T. CSERHATI, S. BALOGH, R. KALISZAN, P. HABER, A. NASAL, (Hungarian Acad. of Sciences, Inst. of Chem., Chem. Research Center, P.O. Box 17, 1525 Budapest, Hungary)

      Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 183-193. The retention behavior of 7 monotetrazolium and 9 ditetrazolium salts were studied by spectral mapping technique. Tetrahydrofuran has the highest solvent strength while the differences among ethanol, 1-propanol, 2-propanol and dioxane were relatively low. The selectivity of tetrahydrofuran was different from those of others. Hydrophobicity and electronic parameters were equally involved in the retention strength and selectivity indicating the mixed character of their interaction with the alumina stationary phase and impregnated one.

      Retention-mobile phase relationships for methylxanthines and biogenic amine metabolites in adsorption thin-layer chromatographic systems
      Irena BARANOWSKA*, M. ZYDRON (*Department of Analytical and General Chemistry, Silesian University of Technology, 7 M. Strzody Str., 44-100 Gliwice, Poland)

      J. Planar Chromatogr. 17, 233-237 (2004). TLC of biogenic amines (dopamine, adrenaline, noradrenaline, 3-methoxytyramine, methanephrine, normethanephrine, vanillylmandelic acid, homovanillic acid, 3,4-dihdroxyphenylacetic acid, 3,4-dihydroxyphenylethyleneglycol, 3-methoxy-4-hydroxyphenylethyleneglycol) and methylxanthines (1-methylxanthine, 7-methylxanthine, theophylline, paraxanthine, theobromine, caffeine) on silica gel with mobile phases comprising a non-polar or weakly polar diluent (chloroform, heptane, or hexane) and a polar modifier (tetrahydrofurane, dioxane, acetone, or ethyl acetate). Examination under UV light or detection with a solution of iron(III) chloride (5 g) and iodine (2 g) in 50 mL of 20 % aqueous tartaric acid.
