Description

Quantitative Organic Microanalysis, Second Edition presents the recommendations of the American Chemical Society group for specification and methods of organic microanalysis.
This book is organized into 23 chapters, and starts with discussions on test samples, blank tests, second type of efficient vibration-absorbing balance table, and microchemical balances. Other general topics covered include the Kjeldahl procedures to determine nitrogen compounds; oxygen flask combustions; determination of fluorine; and microhydrogenation. The final chapters present the modification of the procedure for the determination of oxygen using gravimetry.
This book will be of great value to microanalysts, researchers, and college students who wants to expand their understanding in organic microanalysis.
