Rezensionen
Experienced analysts in this field will find information and guidance in this book that they may not have known or may have forgotten....a thorough coverage of modern surfactant anaylsis. It would be a very useful addition to the library of any laboratory doing surfactant analysis o Inform d September 1994; This book will provide both the novice and experienced chemist with a clear, well-structured introduction to surfactant analysis. The text achieves a good balance between the theoretical aspects of the chemistry and sound practical instruction. The recommended techniques are often accompanied by useful advice obviously derived from extensive experience...an excellent introduction to the field... - Analytica Chimica Acta
