Book excerpt: Ever since the boom of spectrum analysis in the 1860s, spectroscopy has become one of the most fruitful research technologies in analytic chemistry, physics, astronomy, and other sciences. This book is the first in-depth study of the ways in which various types of spectra, especially the sun's Fraunhofer lines, have been recorded, displayed, and interpreted. The book assesses the virtues and pitfalls of various types of depictions, including hand sketches, woodcuts, engravings, lithographs and, from the late 1870s onwards, photomechanical reproductions. The material of a 19th-century engraver or lithographer, the daily research practice of a spectroscopist in the laboratory, or a student's use of spectrum posters in the classroom, all are looked at and documented here. For pioneers of photography such as John Herschel or Hermann Wilhelm Vogel, the spectrum even served as a prime test object for gauging the color sensitivity of their processes. This is a broad, contextual portrayal of the visual culture of spectroscopy in the 19th and early 20th centuries. The illustrations are not confined to spectra--they show instruments, laboratories, people at work, and plates of printing manuals. The result is a multifacetted description, focusing on the period from Fraunhofer up to the beginning of Bohr's quantum theory. A great deal of new and fascinating material from two dozen archives has been included. A must for anyone interested in the history of modern science or in research practice using visual representations.

Download or read book Methods in Food Analysis written by Maynard Joslyn and published by Elsevier. This book was released on 2012-12-02 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods in Food Analysis Applied to Food Products deals with the principles and the acquired tools of food analysis, emphasizing fruit and vegetable products. The book explains the suitability and limitations of the analytical procedures used for food products, from polarimetry and saccharimetry to colorimetry, spectrophotometry, viscosimetry, acidimetry, and alcoholometry. This volume is organized into 20 chapters and begins with an overview of sampling and preparation and preservation of sample. Under the physical methods, the principles of the more common procedures are discussed together with their application to the analysis of fruit and vegetable products. A brief account of the nature of the products is included. In presenting the chemical methods, the salient chemical properties of the constituent are first considered, focusing on those properties used in analysis, which is then followed by an outline of the chemistry of several of the available methods. Finally a detailed description of one of the methods, usually as applied to fruit and vegetable products, is explained. Some references to microanalytical, bioassay and bacteriological procedures are made. This book is intended for food technologists, chemists, and manufacturers; students; and researchers involved in quantitative analyses; organic and inorganic chemistry; and bacteriology.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the state of the art in pharmaceutical applications of UV-VIS spectroscopy. This book presents the fundamentals for the beginner and, for the expert, discusses both qualitative and quantitative analysis problems. Several chapters focus on the determination of drugs in various matrices, the coupling of chromatographic and spectrophotometric methods, and the problems associated with the use of chemical reactions prior to spectrophotometric measurements. The final chapter provides a survey of the spectrophotometric determination of the main families of drugs, emphasizing the achievements of the last decade.

Download or read book Robert Burns Woodward written by Otto Theodor Benfey and published by Chemical Heritage Foundation. This book was released on 2001 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robert Burns Woodward was the star of 20th-century organic chemistry. An MIT graduate by age 19, Woodward's ingenious notions about organic synthesis and his artful methodology were astounding. He is most famed for his synthesis of vitamin B12,which he undertook with Albert Eschenmoser, and for the orbital symmetry rules he developed with Roald Hoffmann. This volume presents Woodward's most celebrated papers and lectures--including the famous Cope lecture. Insightful commentaries and rarely seen photographs are also included.
