Excerpt from Technical Gas-Analysis During the twelve years succeeding the second edition of the Handbook, the methods of Technical gas-analysis have been the subject of numerous investigations and publications which have brought about very important changes in that branch of chemical science. When, therefore, the time had come for issuing a new edition, the Author decided not to go over the old ground again, but to start on a fresh basis, and to describe the methods of Technical gas-analysis in his own way, using Winkler's book merely as one of various sources, apart from his own investigations. The result was the composition of this present treatise, which the Author has tried to make as comprehensive and generally useful as possible, without attempting to mention everything published on the subject in question - a course which would have unduly swelled the size of the volume, without corresponding benefit to the reader. He hopes that his effort may be appreciated as successful by the chemists working on gas-analysis. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
