      New interfaces for coupling TLC with TOF SIMS
      A. ORINAK*, H. F. ARLINGHAUS, G. VERING, M. JUSTINOVA, R. ORINAKOVA, L. TURCANIOVA, M. HALAMA, (*Univ. of P. J. Saf·rik, Inst. of Chem. Sci., Dept. of Physical and Anal. Chem., Moyzesova 11, 040 01 Kosice, Slovakia)

      J. Planar Chromatogr. 16, 23-27 (2003). TLC of a zinc complex stock solution (Zn(CH3CH2COO)2(tu)2 - a complex of zinc butyrate bound to two thiourea molecules) on RP-18, aluminium backed, with methanol - water 2:3. The first interface was formed by vacuum deposition of silver on to the chromatographic layer and onto a channel formed by scraping the layer from the glass plate. The unmodified aluminium backing of a TLC plate (again formed by elution) was used as the second interface. Silver vapor-coated aluminium gave better results.

      Metabolomics of four TCM herbal products
      Olumuyiwa OGEGBO*, S. EYOB, S. PARMAR, Z.T. WANG, Annie BLIGH (*Plantalysis, Institute for Helath Research and Policy, London Metropolitan University, 166-220 Holloway Road, London, UK, o.ogegbo@londonmet.ac.uk)

      Anal. Methods 4, 2522-2527 (2012). HPTLC of the petroleum ether extracts of the herbal TCM root drugs of Aster tataricus, Atractylodes lancea, Gentiana rigescens, and Gentiana macrophylla on silica gel with toluene - ethyl acetate 15:1 over 70 mm. Detection under UV 366 nm and white light after immersion in 1 % vanillin solution dissolved in 10 % conc. sulfuric acid in ethanol, heating at 105 °C for 5 min. Each sample track on the UV 366 nm image was digitalized. For statistical data exploration multivariate analysis based on the models principal component analysis (PCA), partial least-square-discriminant analysis (PLS-DA) and orthogonal PLS-DA was used. The model score plots showed for all three models good spatial distributions with clear cluster for grouping each sample and high reproducibility and predictive values (> 0.5).

      J. Chromatogr. 684, 370-373 (1994). Description of a micro-preparative TLC system. Quantitative elution of the separated spots or linear zones with a fast-moving drill, and by siphoning eluent through a specially formed sintered glass onto one end of the zone or spot and picking up the eluate at the other with a piece of filter-paper carton. Extraction of the latter by soaking and centrifugation. Demonstration of the application in the carbohydrate field.

      Pressurized planar electrochromatography as a supporting tool for qualitative toxicological chemical analysis with thin-layer chromatography and UV-Vis spectrometry
      T. DZIDO*, E. KOPCIAL, J. SZPONAR, A. KRAJEWSKA, L. AFTYKA, J. BAKIERA, B. POLAK, A. KLIMEK (*Department of Physical Chemistry, Faculty of Pharmacy with Medical Analytics Division, Medical University of Lublin, Lublin, Poland, tadeusz.dzido@umlub.pl)

      J. Liq. Chromatogr. Relat. Technol. 40, 320-326 (2017).

The authors showed the application of the migration distance of the solutes, obtained by the PPEC technique, with a proposed equation allowed for increase of likely identification of substances in toxicological analysis.

      A rapid, cost-effective approach to automated TLC method development
      F.L. BIRKINSHAW*, D.G. WATERS, (*SmithKline Beecham, Analytical Sciences, Chemical Development, Tonbridge, Kent, TN11 9AN, UK)

      J. Planar Chromatogr. 8, 319-323 (1995). Application of a test mixture (thymol blue, methyl red, bromothymol blue, oracet blue) on silica with an automatic TLC sampler. Followed by radial development with a selection of solvents also delivered by the automatic TLC sampler. Chromatograms can be obtained by densitometry. Inspection enables selection of the approximate solvent strength (Snyder’s solvent classification table) for the separation. The results indicate which solvent group has the required selectivity. So a suitable solvent system can generally be determined in two to three methodical steps. Rapid, cost-effective method requiring minimal solvent and sample consumption.

      Coupling development and elution, a new thin-layer chromatography technique J
      J. HAN (Han Jing), D. WANG (Wang Dongyuan)*, D. WANG (Wang Dan), Y. WANG (Wang Yuping), M. ZHOU (Zhou Mi), L. LI (Li Ledao), H. ZHANG (Zhang Hongxia) (*Department of Analytical Chemistry, Shenyang Pharmaceutical University, 103 Wenhua Road, Shenyang 110016, China)

      Chromatogr. A 1002 (1-2), 213-219 (2003). Three methods of coupling development and elution were studied in this paper. (1) A new mode of solvent supplementation and eluate collection was developed for descending development. By using a new distributor and collector in descending development, components can be separated and eluted continuously. (2) The same effect can be realized with a slope distributor [Su et al., J. Planar Chromatogr. 14 (2001) 203] and a collector by horizontal development. (3) In-situ elution can be used to treat a developed silica plate, which can elute the separated components to the receptor without scraping them off. These three methods can be used individually, and the in-situ elution can be used with other modes of development.
