Download or read book The Testing of Chemical Reagents for Purity Classic Reprint written by C. Krauch and published by . This book was released on 2015-09-27 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Testing of Chemical Reagents for Purity The necessity of obtaining the highest degree of purity in those reagents which are most largely used in chemical analysis and research, demands a means of speedily recognizing the impurities most often encountered. This means of recognition, together with much general information regarding the various reagents, is afforded in a very comprehensive form by Dr. Krauchs' valuable work, which we present for the first time in English, the translation being that of the third German edition. We have practically adhered to the general arrangement and treatment adopted by the author. We would particularly call the attention of the reader to the fact that, in most instances, reference has been made to English abstracts from the original communications. We have also endeavoured to enhance the value of the book by substituting for the numerous references to German text books on chemical analysis the corresponding English works. We have to acknowledge the valuable aid given by the author himself in supplying us with additions and corrections, the result of his experience since the third German edition was published. The Latin titles of the reagents are those of the Pharmacop a Germanica and have been retained, as they may be of service for the recognition of certain chemicals in price lists. In conducting the various tests, the author emphasises rigid adherence to the degree of concentration, the amount of reagent used and the manner in which the test is to be carried out. Temperatures are, in all cases, given in degrees Centigrade. Finally, our thanks are due to those friends who have assisted us in revising the proofs of this translation.

Available in PDF, EPUB and Kindle. Book excerpt: With about 10–20% of the adult population in Europe being tattooed, there is a strong demand for publications discussing the various issues related to tattooed skin and health. Until now, only a few scientific studies on tattooing have been published. This book discusses different aspects of the various medical risks associated with tattoos, such as allergic reactions from red tattoos, papulo-nodular reactions from black tattoos as well as technical and psycho-social complications, in addition to bacterial and viral infections. Further sections are dedicated to the composition of tattoo inks, and a case is made for the urgent introduction of national and international regulations. Distinguished authors, all specialists in their particular fields, have contributed to this publication which provides a comprehensive view of the health implications associated with tattooing. The book covers a broad range of topics that will be of interest to clinicians and nursing staff, toxicologists and regulators as well as laser surgeons who often face the challenge of having to remove tattoos, professional tattooists and producers of tattoo ink.
Download or read book Handbook of Isolation and Characterization of Impurities in Pharmaceuticals written by Satinder Ahuja and published by Academic Press. This book was released on 2003-07-18 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Food and Drug Administration (FDA) and other regulatory bodies around the world require that impurities in drug substance and drug product levels recommended by the International Conference on Harmonisation (ICH) be isolated and characterized. Identifying process-related impurities and degradation products also helps us to understand the production of impurities and assists in defining degradation mechanisms. When this process is performed at an early stage, there is ample time to address various aspects of drug development to prevent or control the production of impurities and degradation products well before the regulatory filing and thus assure production of a high-quality drug product. This book, therefore, has been designed to meet the need for a reference text on the complex process of isolation and characterization of process-related (synthesis and formulation) impurities and degradation products to meet critical requlatory requirements. It's objective is to provide guidance on isolating and characterizing impurities of pharmaceuticals such as drug candidates, drug substances, and drug products. The book outlines impurity identification processes and will be a key resource document for impurity analysis, isolation/synthesis, and characterization. - Provides valuable information on isolation and characterization of impurities. - Gives a regulatory perspective on the subject. - Describes various considerations involved in meeting regulatory requirements. - Discusses various sources of impurities and degredation products.
Download or read book Beyond the Molecular Frontier written by National Research Council and published by National Academies Press. This book was released on 2003-03-19 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.
