Differential Scanning Calorimetry (DSC) is a well established measuring method which is used on a large scale in different areas of research, development, and quality inspection and testing. Over a large temperature range, thermal effects can be quickly identified and the relevant temperature and the characteristic caloric values determined using substance quantities in the mg range. Measurement values obtained by DSC allow heat capacity, heat of transition, kinetic data, purity and glass transition to be determined. DSC curves serve to identify substances, to set up phase diagrams and to determine degrees of crystallinity. This book provides, for the first time, an overall description of the most impor tant applications of Differential Scanning Calorimetry. Prerequisites for reliable measurement results, optimum evaluation of the measurement curves and esti mation of the uncertainties of measurement are, however, the knowledge of the theoretical bases of DSC, a precise calibration of the calorimeter and the correct analysis of the measurement curve. The largest part of this book deals with these basic aspects: The theory of DSC is discussed for both heat flux and power compensated instruments; temperature calibration and caloric calibration are described on the basis of thermodynamic principles. Desmearing of the measurement curve in different ways is presented as a method for evaluating the curves of fast transitions.

MTDSC provides a step-change increase in the power of calorimetry to characterize virtually all polymer systems including curing systems, blends and semicrystalline polymers. It enables hidden transitions to be revealed, miscibility to be accurately assessed, and phases and interfaces in complex blends to be quantified. It also enables crystallinity in complex systems to be measured and provides new insights into melting behaviour. All of this is achieved by a simple modification of conventional DSC. In 1992 a new calorimetric technique was introduced that superimposed a small modulation on top of the conventional linear temperature program typically used in differential scanning calorimetry. This was combined with a method of data analysis that enabled the sample’s response to the linear component of the temperature program to be separated from its response to the periodic component. In this way, for the first time, a signal equivalent to that of conventional DSC was obtained simultaneously with a measure of the sample’s heat capacity from the modulation. The new information this provided sparked a revolution in scanning calorimetry by enabling new insights to be gained into almost all aspects of polymer characteristics. This book provides both a basic and advanced treatment of the theory of the technique followed by a detailed exposition of its application to reacting systems, blends and semicrystalline polymers by the leaders in all of these fields. It is an essential text for anybody interested in calorimetry or polymer characterization, especially if they have found that conventional DSC cannot help them with their problems.

Differential scanning calorimetry (DSC) is the most important thermal analysis technique used today and the most common thermal analysis instrument found in chemical characterization laboratories. DSC has become an everyday tool in characterization laboratories, but many researchers using this technique have a limited understanding of the true breadth of its capabilities. Up to now, there has been no book that would describe the application of DSC in all the various areas of materials chemistry. The Handbook of Differential Scanning Calorimetry has been written to fill that void. This book is designed to summarize the knowledge of differential scanning calorimetry so that materials researchers and application chemists are given both a better understanding of techniques , as well as a review of the full scope of its capabilities. It also discusses how to properly interpret the DSC thermograms data obtained. Included in this work is the most up-to-date information written by some of the leaders in the field. It is written not only to help users get the most out of their equipment, After reading this book, people in all chemical and biological areas will have a broad overview of this measuring technique, and will be able to utilize this analytical technique more efficiently. - Provides a detail description of the theory behind differential scanning while simultaneously providing a wider breadth of understanding of the actual DSC technique - Includes a review of the basics of heat flux and power compensation DSC's, as well as separate chapters on inorganic and organic materials - Reviews the most common commercial DSC instruments on the market and their uses, including TA Instruments, Perkin-Elmer, Hitachi, Mettler Toledo, Netzsch, and Setaram

Thermal Analysis techniques are used in a wide range of disciplines, from pharmacy and foods to polymer science, materials and glasses; in fact any field where changes in sample behaviour are observed under controlled heating or controlled cooling conditions. The wide range of measurements possible provide fundamental information on the material properties of the system under test, so thermal analysis has found increasing use both in basic characterisation of materials and in a wide range of applications in research, development and quality control in industry and academia. Principles and Applications of Thermal Analysis is written by manufacturers and experienced users of thermal techniques. It provides the reader with sound practical instruction on how to use the techniques and gives an up to date account of the principle industrial applications. By covering basic thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) including the new approach of Fast Scanning DSC, together with dynamic mechanical analysis (DMA /TMA) methods, then developing the discussion to encompass industrial applications, the book serves as an ideal introduction to the technology for new users. With a strong focus on practical issues and relating the measurements to the physical behaviour of the materials under test, the book will also serve as an important reference for experienced analysts.

The design and development of drugs and new pharmaceutical formulations require a full characterization of the chemical and physicochemical events occurring at the level of the single active ingredients or excipients, as well as their reciprocal interaction. Thermal analysis techniques are among the most widely used methods to achieve this; among them, the Differential Scanning Calorimetry (DSC) technique, in which the thermotropic behaviour of a single substance or mixtures is analyzed as a function of a controlled temperature program. DSC is an accurate and rapid thermo-analytical technique, widely used by the pharmaceutical industry and in drug research to investigate several physico-chemical phenomena, such as polymorphism, melting and crystallization, purity, and drug-excipient interaction; as well as characterizing biomolecules such as genetic material.Drug-biomembrane interaction studies is written by scientists renowned for their work in the field of DSC applications to drug development and delivery, and especially to drug-biomembrane interaction studies. The book combines insights from biochemistry and physiology with those from structural biology, nanotechnology and biothermodynamics, to obtain a complete depiction of cell membranes and their functions. - Summarizes and updates the recent development in a unique handbook format - Consists of a combination of scientific updates within the field - Contains chapters written by some of the highest-level experts in the field of DSC
