      J. Chromatogr. 435, 397-416 (1988). Study of the formation of multiple fronts when pure liquids such as methanol and heptane and multi-component liquids such as ethanol - toluene mixtures flow through dry TLC layers of silica or octadecyl-silica. Measurement of the dynamics, and explanation of the formation and motion by using a model.

      The influence of layer porosity on the flow resistance and apparent particle size of thin-layer chromatography plates
      W.P.N. FERNANDO, C.F. POOLE*, (*Dept. of Chem., Wayne State Univ., Detroit, MI 48202, USA)

      J. Planar Chromatogr. 3, 389-396 (1990). Forced flow development (OPLC) was used to determine the porosity, permeability, and apparent average particle size of commercially manufactured TLC plates and Empore sheets. Compared with columns, layers exhibit smaller values for the total porosity (eT - 0.69) and interstitial porosity (e U - 0.42).

      Chromatographia 34, 431-432 (1992). Reverse-phase TLC of porphyrin ether glycerides on RP-18 silica with acetone - methanol 1:1, and paraffin oil - impregnated silica with acetone - methanol 1:1. Also HPLC. Supplementary physico-chemical characteristics are given for the compounds.

      Prediction of retention data in multiple development
      B. SZABADY, M. RUSZINKO, S. NYIREDY*, (Res. Inst. for Med. Plants, H-2011 Budakalasz, P. O. Box 11, Hungary)

      Part I. Linearly increasing development distances. J. Planar Chromatogr. 8, 279 - 283 (1995). Determination of the value RFn, the retention factor after the nth development step (i.e. the ratio of the total migration distance of the component during consecutive development steps to the chromatographic distance of the last development step). The zone width dn of a given spot (after the nth step) is also predicted. The elaborated models are supported with experimental results. - TLC and HPTLC of mixtures of furocoumarin isomers, cannabinoids, and poppy alkaloids (isopimpinellin, xanthotoxin, bergapten, psoralen, angelicin; cannabigerol, cannabichromene, cannabidiol; morphine, codeine, narcotoline, thebaine, papaverine, narcotine) on silica with chloroform and toluene as monocomponent mobile phases for furocoumarins and cannabinoids, resp. chromatography of poppy alkaloids was performed with ethyl acetate - acetone - hexane - methanol - dichloromethane - diethylamine 113:113:226:19:19:1. Detection and evaluation under UV 313 nm for furocoumarin isomers, at 200 nm for cannabinoids, and at 280 nm for alkaloids.

      Investigation by photoacoustic spectroscopy of the effect of drying conditions on the depth-distribution of compounds on TLC plates
      I. VOVK, M. FRANKO* J. GIBKES, M. PROSEK, D. BICANIC, (*School of Env. Sci., P.O. Box 301, 5001 Nova Gorica, Slovenia)

      J. Planar Chromatogr. 11, 379-382 (1998). Photoacoustic spectroscopy (PAS) has been used to investigate the influence of the plate-drying process (in a dryer, in a current of warm air, or in ambient air) on the depth-distribution of compounds inside the sorbent layer of TLC plates. The results obtained by PAS studies from different TLC plates were compared with those obtained by reflectance mode slit-scanning densitometry. Use of different drying conditions resulted in significant differences between PAS signals obtained from the same compound in the uppermost 62 µm layer of the sorbent. HPTLC of a test dye mixture on silica gel with toluene. Densitometry at 514 nm.

      The role of the lateral analyte-analyte interactions in the process of TLC band formation
      W. PRUS, K. KACZMARSKI, K. TYRPIEN, M. BORYS, T. KOWALSKA*, (*Inst. of Chem., Silesian Univ., 9 Szkolna Street, Katowice, Poland)

      J. Liq. Chrom. & Rel. Technol. 24, 1381-1396 (2001). Investigation of intermolecular hydrogen-bonding interactions among adsorbed analyte molecules (i.e. so-called lateral interactions) and their real impact on the retention process. To this effect, two different models were elaborated, taking into account the aforementioned interactions. The validity of the two models was checked experimentally with three higher fatty acids as test solutes. The results obtained fully confirmed the practical usefulness of the two approaches. TLC of dodecanoic, tetradecanoic, and hexadecanoic acid on cellulose with decalin. Visualization by spraying with ethanolic bromocresol green solution. Quantification by densitometry at 625 nm.
