Excerpt from Handbook of Technical Gas-Analysis Every one who has to make gas-analyses for technical purposes is aware that Professor Clemens Winkler is the founder of technical gas-analysis as a distinct branch of analytical Chemistry. A few such processes were, of course, previously known and practised; but Winkler was the first to draw attention to the importance of this subject, to invent suitable apparatus, and to elaborate a complete system of qualitative and quantitative technical gas-analysis, containing a vast number of new observations and methods, along with a very complete description of the work already done in the same direction by others. The field first opened out by Winkler has been very successfully cultivated by other chemists; and it is now quite usual, at any rate in Germany, to perform technical gas-analyses, not merely in chemical works, but for testing the efficiency of steam-boiler furnaces and such purposes. In England some of these processes have also been introduced; but they are not as yet known and appreciated to the same extent as abroad. Hence it may not be unwelcome to English chemists to have a translation of a short treatise, just published by Winkler, which is primarily intended for teaching purposes - that is, for the use of teachers and students in public laboratories - but which likewise serves as a guide and a handy book to other chemists wishing to make themselves acquainted with the subject. This treatise is not intended, as was its predecessor, to furnish a complete enumeration of all apparatus hitherto proposed for technical gas-analysis, but merely to give representative examples of each kind of apparatus, embracing all the divisions of this branch of Chemistry.
