Available in PDF, EPUB and Kindle. Book excerpt: The Kjeldahl Method for Organic Nitrogen volume presents a broad and comprehensive survey of the method as applied to natural products and organic nitrogen compounds. The quantitative determination of an element as widely distributed as nitrogen is of great importance, and the truth of this is borne out by the tremendous amount of literature published throughout the years. The analysis of nitrogen can be divided into two classes: inorganic and organic. This book is concerned only with organic nitrogen compounds, and specifically their determination by the Kjeldahl method. The book opens with a chapter on the historical background and the work leading to the evolution of the method. This is followed by separate chapters that discuss each of the several divisions of the method, e.g., salt addition, reduction, oxidation, catalysts, distillation.

Download or read book Semimicro Quantitative Organic Analysis written by E. P. Clark and published by Elsevier. This book was released on 2013-10-22 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semimicro Quantitative Organic Analysis focuses on the analytical phase of research and chemistry of natural products, as well as analysis of gases and methods used in identifying iodine and other substances. The manuscript first offers information on the determination of carbon, hydrogen, and nitrogen, and the use of Kjeldahl and Dumas methods in the determination of nitrogen. The book also ponders on the determination of halogens, including the use of ethanolamine-sodium, Carius, and sodium peroxide fusion methods and the Liepert volumetric method for iodine. The publication discusses the determination of sulfur and phosphorus, as well as the alkali-nitrate fusion method for converting organic phosphorus to orthophosphate and Woy's procedure for weighing phosphorus as phosphomolybdic anhydride. The text also reviews the determination of methoxyl and ethoxyl and acetyl groups; determination of neutralization equivalent and molecular weights; and determination of volatile fatty acids. The manuscript is a dependable reference for readers interested in the chemistry of natural products.

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.

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: Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were: 1. the dependence of scientific progress in biology on the improvement of ex isting and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized jour nals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete that it is dif ficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be just as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a way that made description, as applied to plant material, com plete in itself with little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes.
