TLC and HPTLC of aflatoxins (B1, B2, G1, G2) in flour, of peppermint oil (from USA and Japan; menthol, isopulegol, cineole, thymol, menthyl acetate) and of samples of Gingko biloba of different origin (details are available from CAMAG application laboratory). Detection by UV 254 and 366 nm before and after derivatization. TLC is of special importance for e.g. the batch tests in pharmaceutical analysis, for content uniformity tests, for the investigation of drug release of solid pharmaceuticals, for cleaning validation, for residue analysis and for studies of bioavailability. Short and concise description of possibilities.

(Introduction to HPPLC / high pressure planar liquid chromatography). Huethig Publ.Co., Heidelberg, Basel, New York (1987), ISBN 3 7785-1563-2, 256 pages.Description of a novel technique. The stationary phase is a separation layer on glass, to which the mobile phase is fed under medium to high pressure (up to 80 bar). Developing modes are circular or anticircular. Any mobile and stationary phase combination useful in HPLC can be employed. Quantification is possible by either direct image processing (only in the visible range of the spectrum), or by radial scanning with a suitable densitometer (CAMAG). Chapters of the book are: Purpose and description of HPPLC, qualitative application range, quantitative application range, instrumentation, sample dosage, pressure and flow in

Chromatographic Science Series, No. 95, CRC Press - Taylor and Francis Group, Boca Raton, 2006, 424 pp. Designed as a practical, comprehensive source of information on the field of classical preparative layer chromatography (PLC), the monograph is a valuable and important supplement to the existing vast chromatographic literature, demonstrating the potential of PLC for separation and isolation of pure compounds, even from very complex mixtures. The book is organized on two parts, the first of which covers the theory and up-to-date procedures of PLC (chapters 1 through 8), while the second (chapters 9 through 16) includes applications to a selection of the most important classes and sample types. Section I: Introduction; Adsorption Planar Chromatography in the Nonlinear Range: Selected Drawbacks and Selected Guidelines; Sorbents and Precoated Layers in PLC; Selection and Optimization of the Moblile Phase for PLC; Sample Application and Chromatogram Development; Application of Horizontal Chambers; Location of Separated Zones by Use of Visualization Reagents, UV Absorbance on Layers Containing a Fluorescent Indicator, and Densitometry; Additional Detection Methods and Removal of Zones from the Layer. Section II: Medical Applications of PLC; PLC of Hydrophilic Vitamins; Preparative Layer Chromatography of Natural Mixtures; The Use of PLC for the Separation of Natural Pigments; Application of PLC to Inorganics and Organometallics; PLC in a Cleanup and Ground Fractionation of Geochemical Samples; The Use of PLC for Isolation and Identification of Unknown Compounds from the Frankincense Resin (Olibanum): Strategies for Finding Marker Substances.

J. Liq. Chromatogr. Relat. Technol. 35, 1497-1516 (2012). The authors reviewed stationary phases, solvent systems, and detection reagents developed for the analysis of amino acids. Polar and non-polar layers as well as impregnated layers mainly with metal ions and also with chiral agents were described for the separation and identification of amino acids. On the other hand, over fifty mobile phases were reviewed for the analysis of amino acids, with a recent tendency in the use of surfactants as less toxic reagents. Methodologies for the separation of amino acid enantiomers, such as the use of beta-cyclodextrin as chiral mobile phase as well as derivatization methods such as iodine azide reaction to enhance sensitivity in detection were also described. TLC has a privileged position due to its simplicity, convenience, and cost-effectiveness for separation of amino acids.
