This reference gives food science professionals a working understanding of near-infrared spectroscopy (NIRS) and its role in maximizing food potential. It explains the technical aspects of NIRS, including: basic principles; characteristics of the NIR spectra; instrumentation; sampling techniques; and chemometrics. The book details applications of NIRS in agricultural and marine products, foodstuffs and processed foods, engineering and process monitoring, and food safety and disease diagnosis.
Computervalidierung in Labor und Betrieb
Mit Computervalidierung weist man nach, da? Software und Hardware das tun, was sie tun sollen. Dieser Nachweis ist nicht nur eine Forderung von Qualitatssicherungssystemen wie GCP (Good Clinical Practice), GLP (Good Laboratory Practice) oder GMP (Good Manufacturing Practice). Auch die Zertifizierung (ISO 9000), Akkreditierung (EN 45000) und die Qualitatssicherung im Lebensmittelbereich (HACCP) erfordern entsprechende Ma?nahmen. Mit diesem Buch liegt erstmals ein umfassendes Werk zu diesem Thema in deutscher Sprache vor. Jeder, der sich mit dieser Problemstellung konfrontiert sieht, erhalt verstandliche Anleitungen zur praktischen Umsetzung. Im Buch wird gezeigt, wie eine Validierungsorganisation zweckma?ig und wirtschaftlich aufgebaut und dokumentiert werden kann. Davon profitieren Betriebsleiter in der Herstellung von Pharmaka, Chemikalien, Pflanzenschutzmittel, Kosmetika oder Lebensmittel ebenso wie Laborleiter in Forschungs- und Entwicklungsabteilungen, Analytik und Qualitatskontrolle.
Iron Oxides in the Laboratory
Iron Oxides play an important role in numerous disciplines. Since the publication of the first edition, there has been a surge of interest in synthetic fine to ultrafine iron oxides in a wide range of scientific and technological disciplines, especially in mineralogy, geosciences and environmental science and in various branches of technology. As before, the main aim of the second edition is to present reliable, well-tested, up-to-date methods of synthesizing pure iron oxides. The section on monodispersed particles, presently of great interest to industry, has been expanded. Furthermore the methods of characterization have been focused on their relevance to iron oxides. The well tried syntheses have been retained and some new ones have been incorporated.
Reference Materials for Chemical Analysis
There are many academic references describing how RMs are made, but few that explain why they are used, how they should be used and what happens when they are not properly used. In order to fill this gap, the editors have taken the contributions of more than thirty RM practitioners to produce a highly readable text organized in nine chapters. Starting with an introduction to historical, theoretical and technical requirements, the book goes on to examine all aspects of RM production from planning, preparation through analysis to certification, reviews recent development areas, RMs for life analysis and some important general application fields, considers the proper usage of RMs, gives advice on availability and sources of information and lastly looks at future trends and needs for RMs. This book is intended to be a single point of information that both guides the reader through the use of RMs and serves as a primary reference source. It should be on the reading list of anyone working in an analytical laboratory and be found on the library shelf of all analytical chemical laboratories.
Chemistry for the 21st Century
Here, numerous winners of the Wolf prize from all chemical disciplines provide an overview of the new ideas and approaches that will shape this dynamic science over the forthcoming decades and so will have a decisive influence on our living conditions. This glimpse of the future is naturally based on the findings granted us by the rapid increase in chemical research during the 20th century. It may be said that a silent «revolution» took place, the positive results of which are still not fully predicted. For example, chemists in research laboratories nowadays are able to develop drugs in increasingly short times to treat diseases once thought incurable. They can design new materials that withstand extreme conditions, and predict the properties of compounds that no one has even seen yet. In this exceptional book those breakthroughs of modern chemistry are illustrated and explained by leading scientists. It stems from the high-quality papers given at the prestigious ceremony to accompany the presentation of the 20th Wolf Prize. It is an extraordinary source for every chemist in industry and academia to get an overview of the highlights of modern chemistry.
Chemical Sciences in the 20th Century
Chemistry in the last century was characterized by spectacular growth and advances, stimulated by revolutionary theories and experimental breakthroughs. Yet, despite this rapid development, the history of this scientific discipline has achieved only recently the status necessary to understand the effects of chemistry on the scientific and technological culture of the modern world. This book addresses the bridging of boundaries between chemistry and the other «classical» disciplines of science, physics and biology as well as the connections of chemistry to mathematics and technology. Chemical research is represented as an interconnected patchwork of scientific specialties, and this is shown by a mixture of case studies and broader overviews on the history of organic chemistry, theoretical chemistry, nuclear- and cosmochemistry, solid state chemistry, and biotechnology. All of these fields were at the center of the development of twentieth century chemistry, and the authors cover crucial topics such as the emergence of new subdisciplines and research fields, the science-technology relationship, and national styles of scientific work. This monograph represents a unique treasure trove for general historians and historians of science, while also appealing to those interested in the theoretical background and development of modern chemistry.
Domino Reactions in Organic Synthesis
Domino reactions enable you to build complex structures in one-pot reactions without the need to isolate intermediates- a dream comes true. In this book, the well-respected expert, Professor Lutz Tietze, summarizes the possibilities of this reaction type – an approach for an efficiant, economically benificial and ecological benign synthesis. A definite must for every organic chemist.
Teflon, Post-it und Viagra
Was haben Penicillin und Rontgenstrahlen mit Teflonpfanne und Viagra gemeinsam? Ebenso wie Polyethylen oder die praktischen gelben Post-it-notes wurden sie zufallig entdeckt; die Erfolge ergaben sich «nebenbei», bei der Grundlagenforschung oder auf der Suche nach etwas vollig anderem. So mancher Flop im Labor fuhrte so zu Produkten, die aus unserem heutigen Leben nicht mehr wegzudenken sind. Der allgegenwartige Tesafilm etwa ist letztlich ein verunglucktes Wundpflaster, auf dem man heute sogar Daten wie auf CD-ROMs speichern kann. Und die Teflonpfanne verdanken wir nicht der Raumfahrt, sondern der Suche nach einem neuen Kaltemittel fur Kuhlschranke Diese Geschichten rund um Zufalle in der Forschung, vom bekannten Wissenschaftsjournalisten Martin Schneider lebendig und nuancenreich erzahlt, garantieren jede Menge Lesespa?. Die Reise durch drei Jahrhunderte Entdeckungsgeschichte zeigt, dass auch in der Wissenschaft nicht immer alles nach Plan lauft; selbst die besten Forscher brauchten oft ein Quantchen Gluck, um einen Treffer zu landen.
