LC-GC Europe 14, 311-321 (2002). Description of main practices of TLC, associated detection methods and a selection of applications. Sample application; classical, forced-flow planar chromatography and multiple developments; monitoring; quantitative analysis and validation; homogeneity control and stability studies; analysis and identification of drugs in body fluids; analysis and identification of drug residues; metabolic studies, determination of physicochemical characteristics; comparison with HPLC; drug monitoring (antiepileptics, analgesics, anxiolytics, abuse drugs, antidepressant and antimania agents, antiparkinson drugs, antihistamines, drugs acting on the cardiovascular system, non-steroidal anti-inflammatory drugs, vitamins, medicines for the gastrointestinal tract, anabolics compounds, antidiabetics, cytostatic drugs, antimicrobial agents, steroids); medicinal plants and their extracts. According to the authors the vast majority of applied methods involve classic TLC; however, both forced-flow TLC and planar electrophoresis are gaining in importance.

The Royal Society of Chemistry, Cambridge 2005, ISBN 0-85404-535-X This book covers basic theory, concepts and practice of modern thin-layer chromatography. The author summarizes current knowledge obtained by many researchers working on qualitative and quantitative planar chromatography. The manual consists of eight chapters describing each step of typical planar chromatographic process with separate sections devoted to key analytical problems like stationary phase choice and pretreatment, mobile phase optimization, sample preparation and application, plate development and finally spot visualization, detection and quantification. The compact form of this work makes it a really simple, helpful and comprehensive introduction to modern thin-layer chromatography.
