analysis and the smog problem was the subject of a well attended symposium at the Seventh Detroit Anachem Conference held here at Wayne State University's new McGregor Memorial Conference Center, October 26 to 28. Upward of 400 analytical chemists from various parts of the country attended the 3-day meeting. In addition to 30 technical papers, 33 manufacturers and distributors exhibited instruments and apparatus of interest to analytical chemists. The Anachem Conference, originally established in 1953 to provide an op-
portunity for local analytical chemists to describe their work in industrial and academic laboratories, has been expanded in scope from one day to a 3-day meeting. In addition to technical papers, an award has been given each year to an outstanding analytical chemist. The sixth and seventh conferences have also featured exhibits by instrument manufacturers. The meetings are held in various universities and industrial facilities in the Detroit area. Air Pollution. In order to eliminate smog in such cities as Los Angeles, the first step was to make chemical studies of the pollutants and then determine the reactions which produce them. D. M. Teague, Chrysler Corp., said that an industry-wide program has been in effect to reduce the automobile exhaust contribution to smog. This has resulted in new analytical techniques and instruments to measure continuously the complex compounds in exhaust gas under average driving conditions. The effectiveness of corrective devices is then measured in terms of total reduction of hydrocarbons. Among detectors described is one which measures methane, propane, butène, ethylene, acetylene, and benzene together with C 0 2 and H 2 0 . The C 0 2 and H 2 0 interfere and reduce accuracy. This Beckman LB Model 15A gas analyzer (formerly Liston-Becker analyzer) is used as a portable instrument for studying exhaust gases from cars. The only practical means for continuous analysis of exhaust gas appears to be the nondispersive infrared analyzer reported by J. W. Bozek of
