Download or read book The Kjeldahl Method 140 Years written by Jaime Aguirre and published by Springer Nature. This book was released on 2023-07-05 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive survey of the Kjeldahl method and its modifications. It covers all relevant topics, including sample digestion and its variables, distillation and determination of ammonia, equipment development, and concludes with a review of the literature published on the method. Since its introduction in 1883, the Kjeldahl method has been an essential analytical tool for nitrogen determination in research, academic and industrial laboratories. This makes the history of the Kjeldahl method of outstanding relevance to graduate students, postgraduate students, researchers, teachers, and laboratory staff in the fields of analytical chemistry, food/feed analysis, animal/human nutrition, soil/water analysis, and so forth. "This method has probably been applied in one modification or another to every possible form of nitrogen, and in perhaps more laboratories than almost any other single type of analytical method" (Kirk, 1950).

Available in PDF, EPUB and Kindle. Book excerpt: In 1883 Johan Kjeldahl developed a system for nitrogen determination in organic substances. Soon after its publication numerous modifications and improvements were made by different chemists. Throughout the years, thousands of different papers have been written on the process, including suggested variations, upgrades, criticisms, and reviews, and many types of devices have been designed for both the digestion and the distillation stages. Since its introduction in 1883, the Kjeldahl method has been an essential analytical tool for nitrogen determination in research, academic and industrial laboratories.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Anion Determination is a guidebook that details various methods that can be employed in determining anions. The book is comprised of 62 chapters that are organized into four parts. The text first covers general anions, which include fluorosilicate, perruthenate, and vanadate. The second part deals with halogen anions, such as perchlorate, perbromate, and iodide. Part III presents phosphorus oxyanions, including orthophosphate, monofluorophosphate, and hexafluorophosphate. The last part covers sulfur anions, which include peroxodisulfate, polysulfide, and polythionates. The book will be of great use to scientists from a wide range of scientific disciplines, including biology, physics, metallurgy, and engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Aureolus Theophrastus Bombastus von Hohenheim (1493-1541), commonly called Paracelsus, was both one of the most original medical thinkers of the sixteenth century and was the man who made opium (as laudanum), arsenic, copper sulphate, iron, lead, mercury, potassium sulphate, and sulphur part of the pharmacopoeia. A man of many parts, but a pioneer chemist, Paracelsus can be regarded as the originator of a body of work which was the precursor of chemical pharmacology and therapeutics. To no small extent he stands, therefore, as a father figure of the modern pharmaceutical industry. Today's physician who wants to look at that industry since the days of Paracelsus and weigh the great gains against the problems soon encounters difficulties. To diminish them, this Enquiry approaches its subject from historical principles. This gives increased perspective to questions asked late in the boo- these questions being prompted by medical practice outside the industry and some twenty years of drug development activity within it. In antiquity medicines often seem to have been used as part of magic and primitive man thought disease to be due to supernatural forces which he could influence. The legacy remains - and in trying to sort out what is rational in our use of drugs today we have to separate our small bits of science from the ancient magic and from modern commercial pressures and conditioning.
