I t is therefore hardly surprising that thin-layer chromato-graphy has rapidly achieved popularity and that there is already an extensive body of data illustrating the usefulnessof the method.This book will soon be indispensible to all chemists, biologists, and pharmacists who use chromatography and willalso help to opcn up further applications of thin-layer chromatography.(Angewandte Chemic - International Edition)Dr.Randerath has written a clear and concise monograph that provides a practical and theoretical discussion ofthin-layer chromatography (TLC) covering both quantitative and qualitative aspects of this technique. He has at-tempted to review pertinent references in the rapidly expanding list and has included an introductory chapter on thehistorical background that has led to the prcsent-day versatile application of this technique in all chemical andbiological disciplincs. Thc procedures and results for a wide variety of scparations are described in sufficient detailto permit duplication of methods recorded in the literature.Dr. Randerath’s book is intended for the research worker, but it will also be an excellent refercnce for college chem-istry courses such as organic qualitative analysis and general biochemistry.(Chemical Education)Translated from the German b~ D.
