Die lange erwartete, vierte Auflage des Lehrbuchklassikers zur IR-Spektroskopie! Will man Substanzen eindeutig charakterisieren und auf ihre Reinheit berpr fen, f hrt kein Weg an der IR-Spektroskopie als Analysemethode vorbei. Pr zise und leicht verst ndlich, aktuell und sehr praxisbezogen lernen die k nftigen Anwender alles, was sie ber die IR-Spektroskopie wissen m ssen: - Aufbau und Handhabung von Spektrometern, - Vorbereitung der Proben und deren Messung, - qualitative Interpretation der Spektren, - quantitative Bestimmungen, - spezielle Anwendungsgebiete und - spezielle und verwandte Methoden. Zahlreiche Hinweise auf weiterf hrende Literatur vermitteln eine gute Orientierung bei speziellen Fragestellungen, und helfen dabei, sich zum Experten weiterzuentwickeln.

Updated and with approximately 25% new content, this textbook covers the latest developments, including instrumentation for microscopy and imaging, as well as current applications.The authors adopt a didactic approach, introducing infrared spectroscopy in a clear and well-structured way to provide students with a solid background in the principles and knowledge for efficiently using the method to obtain reliable results. Both beginners and experts will find up-to-date references for further reading.A must-have for advanced students (Master's and PhD) as well as those wanting to learn how the method works and how to work with it, including scientists from private and governmental labs.

Die fünfte Auflage dieses Lehrbuchklassikers wurde umfangreich erweitert und ergänzt. Neben aktuellen Entwicklungen im Bereich der IR-Spektroskopie werden auch instrumentelle Neuerungen im Bereich der Mikroskopie und Bildgebung vorgestellt.Das gesamte Themengebiet dieser Analysenmethode wird klar strukturiert und verständlich vermittelt. Beginnend bei den technischen und theoretischen Grundlagen begleitet dieses Buch bereits den Studenten, ist aber aufgrund der praktischen Anwendungsbeispiele und Spezialmethoden auch für routinierte IR-Spektroskopie-Experten ein wichtiges Nachschlagewerk.Dieses Buch erklärt dem Anwender alles, was er für die Charakterisierung und Quantifizierung von Substanzen mit der IR-Spektroskopie wissen muss.

Metrological traceability of chemical measurement results means the establishment of a relation to metrological stated references through an unbroken chain of comparisons. This volume collects 56 outstanding papers on the topic, mostly published in the period 2000-2003 in the journal "Accreditation and Quality Assurance". They provide the latest understanding, and possibly the rationale why it is important to integrate the concept of metrological traceability including suitable measurement standards such as certified reference materials, into the standard measurement procedures of every analytical laboratory. In addition, this anthology considers the benefits to both the analytical laboratory and the user of the measurement results.

It is now becoming recognized in the measurement community that it is as important to communicate the uncertainty related to a specific measurement as it is to report the measurement itself. Without knowing the uncertainty, it is impossible for the users of the result to know what confidence can be placed in it; it is also impossible to assess the comparability of different measurements of the same parameter. This volume collects 20 outstanding papers on the topic, mostly published from 1999-2002 in the journal "Accreditation and Quality Assurance." They provide the rationale for why it is important to evaluate and report the uncertainty of a result in a consistent manner. They also describe the concept of uncertainty, the methodology for evaluating uncertainty, and the advantages of using suitable reference materials. Finally, the benefits to both the analytical laboratory and the user of the results are considered.

Quality assurance and accreditation in analytical chemistry laboratories is an important issue on the national and international scale. The book presents currently used methods to assure the quality of analytical results and it describes accreditation procedures for the mutual recognition of these results. The book describes in detail the accreditation systems in 13 European countries and the present situation in the United States of America. The editor also places high value on accreditation and certification practice and on the relevant legislation in Europe. The appendix lists invaluable information on important European accreditation organizations.
