“…When a simultaneous determination of sulfur (17) and chlorine or bromine is attempted, one of these elements usually is found quantitatively at the expense of the other. The explanation lies in the fact that the lowest temperature, 450°C ., recommended for the quantitative reaction of sulfur trioxide wdth the silver gauze to form silver sulfate is too high for complete retention of either silver chloride or silver bromide.…”

The paper reviews methods of sulphur determination over the last 120 years. Classical methods are presented in a historical view, and the present state of automatic procedures of sulphur estimation is discussed. 104 key references concerning sulphur analysis are cited. On the basis of the present level of the development of elemental analysis, a prognosis of directions of the development of sulphur microanalysis is attempted.

“…According to Stragand and Safford, sulfur in organic compounds can be determined by burning the sample in an atmosphere of oxygen in the presence of a platinum catalyst (283). The sulfur trioxide formed is adsorbed by a silver gauze with the quantitative formation of silver sulfate.…”

THE scope of the present discussion is essentially the same as that established in the first review of inorganic microchemistry (314). Most of the references to developments in such fields as polarography, light microscopy, electron microscopy, fluorometry, nucleonics, and spectrometry are left for more detailed discussion in accompanying reviews, although strictly speaking, they represent true examples of important microchemical techniques. Likewise, most of the developments of applied microchemical methods are left to the reviews of analytical progress in the various industrial fields. BOOKS AND REVIEWSProgress in any field is greatly influenced by the appearance of authoritative books. A noteworthy contribution in the field of microchemistry is the recent appearance of the book "Specific, Selective and Sensitive Reactions" by Feigl (72). This book is unique in that it is an unusually complete record of the profound knowledge and experience of its author; it is not a mere abstract of collected papers but is a critical development of chemical theories based on intimate knowledge of the literature of analytical chemical researches. The book deals mainly with the chemistry of coordinated compounds, including such topics as complex ions and molecules, organic reagents, masking and demasking, induced and catalyzed reactions, surface effects, fluorescence, and photoreactions. No corresponding material has ever been presented in one place before and it seems safe to say that there is no one in the field of microchemistry who could not profit through
