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.
