Аннотация

The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects – properties, synthesis, reactions, physiological and industrial significance – of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.

Quality has become a decisive factor for the success of analytical laboratories as they strive for product quality assurance. In this book leading experts examine for the first time the different aspects of quality as a whole. The work is thus a comprehensive and basic handbook for everybody working in a laboratory. First the quality assurance systems relevant for the individual laboratories are presented and compared with one another. In the second part, the authors describe the measures which allow the reader to objectively judge, evaluate and increase 'quality'. The book concludes with a valuable overview of the importance and meaning of quality.

Anwender der HPLC benotigen ein breites theoretisches und praktisches Wissen. In diesem Buch wird beides vermittelt. Es erklart Theorie, apparative Grundlagen, die verschiedenen HPLC-Prinzipien von Adsorptions- bis Affinitatschromatographie sowie Spezialgebiete wie beispielsweise die Trennung von Enantiomeren. Durchgehend illustriert mit nahezu 200 Abbildungen, davon viele Trennbeispiele. Zahlreiche Ubungsaufgaben dienen zur Vertiefung des Stoffs. In die 9. Auflage wurden neue Abschnitte uber die Haltbarkeit von mobilen Phasen, uber Phasensysteme in der Ionenchromatographie und uber Messunsicherheit aufgenommen. Der Text ist mit einer Randspalte gesetzt, die die Kommentare zum Text aufnimmt. So wird die Lesbarkeit deutlich erhoht und trotz der dichten Information bleibt die Ubersichtlichkeit erhalten.

Thin-layer chromatography (TLC) is a powerful, fast and inexpensive analytical method. It has proven its usefulness in pharmaceutical, food and environmental analysis. This new edition of the practical TLC guide features a completely revised chapter on documentation, now including the use of digital cameras. Selected new sorbents and instruments are also introduced. 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.

As incredible as it may sound, nature is still unbeatable and provides us with the most amazing inventions and phenomena, beyond human imagination. Bacteria that produce plastic or electricity, for example, or natural rocket propulsion or algae that may meet the energy needs of future generations with their supplies of hydrogen. How is it that frogs and fish fall from the sky, how does the dust from the Sahara reach the Caribbean and what lies behind the mysteries of the deep-sea methane oases? Yet nature has also invented modern technologies. A natural solar power plant, for example, provides an Antarctic lake with an agreeable water temperature, and the first functioning nuclear reactor existed in Africa two billion years ago. Nature even created the very first laser. Researchers around the globe are increasingly searching for ways of using nature's inventions for developing new products and concepts. One case in point are extremophile bacteria, which thrive at the baking temperature of 140 degrees Celsius. The resulting enzymes should prove fruitful in chemistry. But also chemosensors, which work like a dog's nose, and bulletproof jackets based on spiders' webs are visions that could profit from evolution's treasure trove.
