Hardback. Condizione: New. Analytical pyrolysis is one of the many tools utilized for the study of natural organic polymers. This books describes in three parts the methodology of analytical pyrolysis, the results of pyrolysis for a variety of biopolymers, and several practical applications of analytical pyrolysis on natural organic polymers and their composite materials. Analytical pyrolysis methodology covers two distinct subjects, the instrumentation used for pyrolysis and the analytical methods that are applied for the analysis of the pyrolysis products. A variety of pyrolytic techniques and of analytical instruments commonly coupled with pyrolysis devices are given.The description of the results of pyrolysis for biopolymers and some chemically modified natural organic polymers is the core of the book. The main pyrolysis products of numerous compounds as well as the proposed mechanisms for their pyrolysis are described. In this part an attempt is made to present as much as possible the chemistry of the pyrolytic process of natural organic polymers.The applications of analytical pyrolysis include topics such as polymer detection used for example in forensic science, structure elucidation of specific polymers, and identification of small molecules present in polymers (anti-oxidants, plasticizers, etc.). Also, the degradation during heating is a subject of major interest in many practical applications regarding the physical properties of polymers. The applications to composite polymeric materials are in the fields of classification of microorganisms, study of a variety of biological samples, study of fossil materials, etc. Analytical pyrolysis can also be used for obtaining information on the burning area generate pyrolysates that have complex compositions. Their analysis is important in connection with health issues, environmental problems, and taste of food and cigarettes.Features of this book:. Presents analytical pyrolysis as a uniform subject and not as a conglomerate of scientific papers. Puts together in an organized manner a large volume of available information in this specific field. Provides original results which address subjects with relatively scarce information in literature. Gives original views on subjects such as the parallel between the pyrolytic process and the ion fragmentation in mass spectrometry. Includes the role of pyrolysis in the burning process.The three parts of the book are covered in 18 chapters, each divided into sections. Some sections are further divided by particular subjects. References are given for each chapter, and an effort has been made to include as much as possible from the available representative information. A few unpublished personal results are also included.

Taschenbuch. Condizione: Neu. Neuware - Method Development in Analytical HPLC presents the essential information for understanding the process of developing an HPLC method of analysis. It includes foundational information related to HPLC, as well as discussion of sample types, the properties of analytes and matrices in the samples, and sample preparation. The core of the book describes the best ways for approaching method development in various types of HPLC and the criteria for method optimization and validation. This book provides clear guidance for adopting analytical methods from the literature and describes the development of original methods with selection of the suitable type of HPLC, of specific columns, mobile phase, and detection techniques with an emphasis on the use of mass spectrometry for detection, as well as optimization and validation of the chosen analytical method. The book includes useful details on method development for specific types of chromatography such as RP-HPLC, HILIC, ion exchange, size exclusion, and chiral. Method Development in Analytical HPLC also includes information about green chemistry in analytical methods, computer assisted method development, and other key contemporary aspects of the subject.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Sample preparation is an essential step in many analyses. This book approaches the topic of sample preparation in chromatography in a methodical way, viewing it as a logical connection between sample collection and analytical chromatography. Providing a guide for choosing the appropriate sample preparation for a given analysis, this book describes various ways to process the sample, explaining the principle, discussing the advantages and disadvantages, describing the applicability to different types of samples, and showing the fitness to specific chromatographic determinations.The first part of the book contains an overview of sample preparation showing its relation to sample collection and to the core chromatographic analysis. The second part covers procedures that do not use chemical modifications of the analyte and includes methods for sample dissolution, concentration and cleanup designed mainly for modifying the initial matrix of the sample. This part starts with conventional separations such as filtration and distillation and finishes with more advanced techniques such as solid phase extraction and electroseparations. The third part gives a description of the chemical modifications that can be performed on a sample either for fractionation purposes or to improve a specific property of the analyte. This part includes derivatizations, polymer chemical degradations, and pyrolysis. 942 pp. Englisch.
