      The principles of long distance OPLC, a new multi-layer development technique
      L. BOTZ, S. NYIREDY, O. STICHER*, (*Dept. of Pharmacy, Swiss Fed. Inst. of Technol., (ETH) Zürich, CH-8092 Zürich, Switzerland)

      J. Planar Chromatogr. 3, 352-354 (1990). Proposition of a new OPLC development technique where the separation distance can be freely increased by special arrangements of the layers. Several plates are placed on top of each other to extend the developing distance. The end of the first (uppermost) chromatoplate has a slit-like perforation to enable the mobile phase to flow to a second layer where migration continues until the opposite end of the plate. Arrangements for identical plates, different stationary phases, sample clean-up, simultaneous sample application and reconcentration, preparative development, combination of linear and triangular development modes, at low, medium or high external operating pressures are mentioned.

      J. Planar Chromatogr. 7, 58-62 (1994). TLC of e.g. plant extracts (containing umbelliprenin, imperatorin, bergapten, phellopterin pimpinellin, isopimpinellin, umbelliferone, isobergapten, xanthotoxol) on silica (with preconcentration zone) with diisopropylether - dichloromethane (of increasing eluent strength, with and without different modifiers). Application of isocratic, gradient, and multiple development, as well as simultaneous development using different eluents under different conditions.

      TLC of p-nitroanilines and their analogues with cyclodextrins in the mobile phase
      I.R. POLITZER*, K.T. CROAGO, T. HOLLIN, M. YOUNG, (*Dept. Chem., Xavier Univ. Louisiana, New Orleans, Louisiana 70125, USA)

      J. Chromatogr. Sci. 33, 316-320 (1995). Use of the addition of a-, b-, g-, and hydroxypropyl-b-cyclodextrins to aqueous mobile phases to enhance the migration of p-nitroanilines and their analogues on TLC. Determination of the equilibrium binding constants for the solute-cyclodextrin complexes formed in the mobile phase. Comparison of the results obtained using silica gel and polyamide plates. Urea, which is used to solubilize the cyclodextrins in aqueous solutions, is also found to increase the migration of the compounds.

      J. TOROK, K. KOVACS-HADADY*, E. MINCSOVICS, (*Lajos Kossuth Univ., Dept. Inorg. & Anal. Chem., H-4010 Debrecen, P.O. Box 21, Hungary)

      J. Chromatogr. A 803, 235-239 (1998). Modeling of ion-pair HPLC separations by using continuous OPLC. Study of the distribution of several cationic ion-pairing reagents on the layer with mobile phases containing different quaternary ammonium salts, which volumes varied between 4.5 to 67.5 cm3 equivalent to a 1 to 15 bed volume of the given layer. Measurement of the concentration of the reagents after chromatography in 10 samples of the stationary phase used.

      Two-dimensional TLC with a sorbent gradient for the analysis of Alfalfa root saponins
      M. GLENSK*, Z. BIALY, M. JURZYSTA, W. CISCOWSKI, (Wroclan Med. Univ., Dep. Pharmacognosy, pl. Nankiera 1, 50-140 Wroclaw, Poland)

      Chromatographia 54 (9/10), 669-672 (2001). 2D-TLC of a mixture of saponins obtained from the roots of Medicago sativa with a sorbent gradient, first development on RP-18 and in the perpendicular direction on silica gel. Comparison of the results obtained with those acquired by 2D-TLC on the same monolayer stationary phase. The saponin mixture consisting of 18 components could be separated into 17 individual saponins by conventional 2D-TLC. When using sorbent gradient the spots were spread over a larger surface area of the silica gel plate.

      Single- and multi-channel OPLC separation on non-segmented sorbent bed using flowing eluent wall for operating segmentation
      E. MINCSOVICS*, M. MANACH, L. KECSKES, B. TAPA, D. PAPILLARD, E. TYIHAK, (*OPLC-NIT, Ltd. , Andor u. 60, H-1119 Budapest, Hungary)

      J. Liq. Chrom. & Rel. Technol. 26, 2611-2627 (2003). A new OPLC separation procedure has been developed for single- and multi-channel separation using a non-segmented sorbent bed and flowing eluent wall (FEW) for operating segmentation. The FEW detaches the sorbent bed into active and non-active parts regarding separation during the process. Only mobile phase is introduced into the non-active part, while, for the active part, eluent and also the sample can be admitted, thus the non-homogeneous part of the sorbent is excluded from the separation process. OPLC of ascorbigen, cabbage extract and a dye mixture on silica gel with e.g. chloroform - methanol - acetic acid 90:10:1 resp. toluene. Detection under UV 285 nm.
