A review on the CHN analysis of organic compounds and the CN environmental
analysis is described. The review contains outline of the evolutionary
development of elementary analysis, since Gay-Lussac, Dumas and Liebig era
until a present slate analysis, with computer controlled, fully automated analyzers.
Physical principles of high temperature and low temperature combustions are
discussed. Technical foundations on conjunctions of the high temperature
combustion with chromatographic separations of the ultimate combustion
products of organic samples, is delineated. Commercially available elemental
analyzers are compared and their construction and operating principles are
described. The basic methods of determination of environmental carbon and
nitrogen are discussed. The representative analyzers for environmental carbon and
nitrogen analysis are presented and their operating principles are described.
