“…The sample was pyrolyzed in a stream of helium, the oxygen converted into CO over a special form of carbon at 1000 °C, and separated on a column of molecular sieve 5A with katharometer detection. Roemer, van Osch, Buis, and Griepink (261) described a procedure for the automated determination of milligram amounts of carbon dioxide. The carbon dioxide produced was absorbed into a solution of 0.5M BaCl2 in tert-butyl alcoholwater (1:9) at pH 10.…”

This review follows the previous one (189) and covers the literature and information received by the authors from October 1971 to November 1973. As in the past, it surveys the developments in the determination of the elements in organic materials.Since the commercial CHN analyzers have been on the market for some ten years (186), time is come for an overall evaluation of these automated machines. At the International Symposium on Microtechniques held in University Park, Pa. in August 1973, several practicing microanalysts reported on the performance of the respective apparatus which they had used for long periods. The findings are favorable. At the same time, it is noted that the number of commercial instruments (187, 188) has diminished. Research activities on automation, however, have been vigorous, as evidenced by the papers on coulometric methods, use of ion-selective electrodes, and other elec-
