      Comparison of DIOL bonded silica gel HPTLC plates with underivatized silica gel
      L. WITHEROW, R.J. THORP, I.D. WILSON*, A. WARRANDER, (*I.C.I. Pharmaceuticals, Alderley Park, Macclesfield, Cheshire, UK, SK10 4TG)

      J. Planar Chromatogr. 3, 169-172 (1990). Investigation of the chromatographic behavior of a wide range of compounds (ecdysteroids, dihydroxybenzoic acids, aromatic amines and N-oxides, paracetamol and metabolites) on silica and diol-bonded silica with solvent systems based on chloroform containing varying proportions of ethanol to adjust the eluotropic strength. Clear and useful differences in selectivity between the two layers were observed. The diol phase gave greatly superior results for the chromatography of the dihydroxybenzoic acids as compared to silica gel.

      TLC of amino acids on thin silica gel layers impregnated with transition metal ions and their anions
      R. BHUSHAN, V. PARSHAD, (Dept. of Chem., Univ. of Roorkee, Roorkee - 247667, India)

      J. Planar Chromatogr. 7, 480-484 (1994). TLC of amino acids on silica impregnated with a variety of sulfates, oxides, acetates, thiocyanates, chlorides, carbonates, nitrates of transition metals with butanol - water - acetic acid 4:2:2. The systems reported were considered as improvements with regard to the number of amino acids resolved from a complex mixture and can be used successfully for the analysis of unknown mixtures. Detection by spraying with ninhydrin solution and heating at 80-100 °C for 5-10 min.

      The actual pH values of the stationary phase in ion-pair thin-layer chromatography
      M. LUKACS, G. BARCSA, K. KOVACS-HADADY*, (*L. Kossuth Univ., Dept. of Inorg. and Anal. Chem., P.O. Box 21, 4010 Debrecen, Hungary)

      J. Planar Chromatogr. 10, 342-347 (1997). Study of the pH values of different chromatographic layers, e.g. silica gel and silica gel RP-18, in the presence of ion-pairing reagents with mobile phases containing methanol, water, and tetramethyl- and cetyltrimethylammonium bromide (TMA and CTMA) as ion pair reagents, representing the two major classes (symmetrical and asymmetrical) of this type of cationic compound. Six different methods were used to incorporate the buffer into the chromatographic system. Significantly different pH values were measured depending on the pretreatment of the layers.

      Raman spectroscopic quantification of the extent of hydrolytic cleavage of octyl ligands from the surface of RP-8-type stationary phases in TLC with mobile phase buffers of pH from 1 to 10
      G. KOWALIK, T. KOWALSKA*, (Inst. of Chem., Silesian Univ., 9 Szkolna Street, 40-006 Katowice, Poland)

      J. Planar Chromatogr. 13, 348-353 (2000). Study of the susceptibility of chemically bonded octyl ligands used in TLC to hydrolytic cleavage of the organic ligands from the surface of the silica ligands. The extent of cleavage proved markedly - contrary to former studies with octadecyl ligands - pH-dependent.

TLC of lauric, myristic, palmitic, stearic, and arachidic acid and lauryl, myristyl, palmityl, stearyl, and arachyl alcohols on silica gel, RP-2, RP-8, and RP-18, impregnated with 1, 5, and 10% solutions of squalane and octadecane in hexane, with methanol - water 39:1. Detection by exposure to iodine vapor.

      Optimization of some variables of on-line injection in pressurized planar electrochromatography
      Aneta GRYSINSKA*, P. PLOCHARZ, R. SZCZAP, T. DZIDO (*Department of Physical Chemistry, Medical University of Lublin, Lublin 20-093, Poland, aneta.halka@umlub.pl)

      J. Liq. Chromatogr. Relat. Technol. 36, 2512-2523 (2013). The paper described the influence of several operating variables of online injection into the pressurized planar electrochromatography (PPEC) separation system. Variables that enable narrow and symmetrical peaks such as sample volume, flow velocity, shapes of the grooves and polarization potential were discussed.

      J. Planar Chromatogr. 12, 373-377 (1999). Description of a new multi-applicator for simultaneous deposition of up to 15 samples, successively on several plates of different sizes. Acepromethazine was used as test analyte, and plates were scanned at 375 nm. The multi-applicator furnished reliable results, both qualitatively - good inter-capillary reproducibility, and adaptibility - and quantitatively - satisfactory linearity, reproducibility, correlation with an autosampler.
