This article is a continuation of the previous review (2) and covers the literature from October 1979 to September 1981. An exceptionally large number of research papers were published during this period. As has been mentioned before, the trend is to develop methods for organic elemental analysis at all levels (2). Whereas many studies have been carried out in the determination of the major constituents in organic compounds, reliable automated methods of general applicability are still limited to carbon, hydrogen, and nitrogen. Much attention has been drawn toward trace analysis, particularly for toxic elements present in all kinds of organic materials.
