Applied Thin-Layer Chromatography, 2nd Edition
Why has the prior edition been successful? All steps of the analytical procedure are clearly explained, starting with the choice of a suitable TLC technique and ending with data evaluation and documentation. Special emphasis is put on the proper choice of materials for TLC. Properties and functions of various materials and the TLC equipment are described, covering e. g. precoated layers, solvents and developing chambers, including information on suppliers. Many practical hints for trouble shooting are given. All this is illustrated with numerous coloured figures.
How to use TLC in compliance with GLP/GMP regulations is described in detail, including the required documentation. Therefore the reader can very easily compile his own standard operating procedures.
