      Strategy for separation of complex mixtures by multidimensional planar chromatography
      T. TUZIMSKI (Medical University of Lublin, Faculty of Pharmacy, Department of Physical Chemistry, Staszica 6, 20-081 Lublin, Poland; tomasz.tuzimski@am.lublin.pl)

      J. Planar Chromatogr. 21, 49-54 (2008). Report of a new procedure for separation of complex mixtures by combining different modes of multidimensional planar chromatography on silica gel plates. Initially the complex mixture was separated into five groups of compounds. Mobile phases for separation of these different groups were then optimized by regarding each group as individual separation problem. By use of this new procedure 22 compounds from a complex mixture were separated on 10 x 10 cm TLC and HPTLC plates. TLC and HPTLC of 22 pesticides on silica gel with ethyl acetate - n-heptane 23 for TLC and 11 for HPTLC in the first direction. After removal of some of the adsorbent layer five further development steps with different eluents followed resulting in the complete separation of the 22 compounds of interest . Detection under UV 254 and 366 nm.

      (Dünnschichtchromatographie mittels Dioden-Array Detektion). GIT Spezial Separation I/2001, 37-39 (2001). Development of a HPTLC scanner for the measurement of spectra between 198 and 612 nm using a diode array detector. Quantitative HPTLC of caffeine on silica gel with isopropanol - cyclohexane - 25% NH3 721 and of uric acid, cytosine, guanine, caffeine, adenine, uracil and thymine on silica gel with isopropanol - toluene - 25% NH3 631. Measurement of 450 single spectra between 200 and 400 nm within 225 s.

      Attenuated total reflectance as an alternative of diffuse reflectance infrared detection in the identification of compounds separated by thin layer chromatography
      D. SZIKRA*, I.P. NAGY (*Department of Physical Chemistry, University of Debrecen, Hungary; deeezs@yahoo.com)

      J. Liq. Chromatogr. Relat. Technol. 31, 161-168 (2008). TLC of 37 compounds, i. a. nitrotoluene, on silica gel, aluminium oxide, cellulose, and silanized silica gel after a short (few centimeters) elution with different eluents. After precise positioning, attenuated total reflectance (ATR) is used for measuring the spots against air background in the range of 650-4000/cm. Diffuse reflectance (DRIFT) and ATR are infrared sampling methods, based on the detection of infrared radiation reflected by the sample. They are widely used in surface analysis and are both capable of detecting small amounts of organic compounds. DRIFT is a well known on-layer method for the identification of analytes, separated on thin layers. In the present work, the possibility of using a diamond ATR unit to collect IR spectra of sample spots is examined.

      Preliminary results of a collaborative study of overpressured derivatization
      H. BONNIER, P. DELVORDRE, E. POSTAIRE*, (in collaboration with 9 co-workers) (*School of Pharmacy, Dept. of Clin. Pharmacy and Biotechnique, 5 rue J.-B. Clément, F-92290 Chatenay-Malabry, France)

      J. Planar Chromatogr. 7, 117-121 (1994). HPTLC and TLC of amino acids, sugars, cardiotonic heterosides on silica with common eluents. Derivatization by pressing a pad of polymeric foam containing the reactive solution on to the chromatographic plate in order to obtain homogeneous and complete distribution of the reagent over the whole plate. Comparison with spraying and dipping.

      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 23. 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 application of HPTLC analysis. 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 151 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).
