he 197th National Meeting of the American Chemical Society will be held in Dallas, TX, April 9-14. At the meeting, the Division of Analytical Chemistry will sponsor or cosponsor technical sessions at which more than 150 presentations are scheduled. In addition to the technical program, the meeting will feature a presidential plenary session entitled "Environmental Issues in Biotechnology—Governmental, Academic, and Industrial Perspectives" (Monday, April 10) and a career development tutorial that will provide information on career guidance, assessment, planning, and options in the chemical industry and elsewhere (Sunday, April 9, and Monday, April 10). Other features of interest will be meetings of the ACS council and board of directors; ACS short courses; a national employment clearinghouse; and a series of social events, including the ACS mixer (Wednesday, April 12), an alumni hour (Tuesday, April 11), and the Division of Analytical Chemistry dinner (Tuesday, April 11). On-site registration facilities will be located in the Dallas Convention Center, East Lobby. The hours for registration will be Sunday, April 9, from 2 P.M. to 7 P.M.; Monday, April 10, through Thursday, April 13, from 7:30 A.M. to 3:30 P.M.; and Friday, April 14, from 7:30 A.M. to 10 A.M. An exposition of instruments, chemicals, technical literature, and other products and services will run for three days in conjunction with the meeting. The exposition, which will be housed in the Dallas Convention Center, will be open Monday, April 10, to Wednesday, April 12, from 8:30 A.M. to 5 P.M. The Division of Analytical Chemistry program includes the following symposia: the ACS Award in Analytical

Chemistry, the Frank H. Field and Joe L. Franklin Award for Outstanding Achievement in Mass Spectrometry, and the ACS Award in Chromatography. Other sessions that are scheduled cover the following topics: chromatographic instrumentation and practice, electrochemistry and surface science, electroanalysis with chemically modified electrodes, separations science and mass spectrometry, applications of microelectrodes to chemistry, and general topics. The Division of Analytical Chemistry will cosponsor two additional symposia: photochemical and electrochemical surface science: microstructural probes of electrode processes (cosponsored with Colloid and Surface Chemistry) and analytical applications of nuclear chemistry—ACS Award for Nuclear Chemistry symposium (cosponsored with Nuclear Chemistry and Technology). All technical sessions sponsored by the Division of Analytical Chemistry and the cosponsored symposium on analytical applications of nuclear chemistry will be held in the Hyatt Regency. The symposium on photochemical and electrochemical surface science will be held in the Convention Center. The analytical chemistry program will be highlighted by the presentation of several awards. Fred Anson, recipient of the ACS Award in Analytical Chemistry, will deliver a talk on Monday, April 10, entitled "Electroanalytical Chemistry and Electroanalytical Chemists—Some Reflections and Observations." The ACS Award in Chromatography will be presented to Fred Régnier, who will deliver a talk entitled " H P L C of Biopolymers: The Past, Present, and Future" on Thursday, April 13. Fred McLafferty, this year's

recipient of the Frank H. Field and Joe L. Franklin Award for Outstanding Achievement in Mass Spectrometry, will deliver his award address, "Mass Spectrometry—Toward the Universal Analytical Method," on Wednesday, April 12. Ronald Macfarlane, recipient of the ACS Award for Nuclear Chemistry, will deliver a talk entitled "He Jets, β Recoils, and a Search for Super-Hea­ v y . . . Molecular Ions" on Monday, April 10, at the symposium on analyti­ cal applications of nuclear chemistry. The ACS Award in Colloid or Surface Chemistry will be presented to Arthur Hubbard, who will deliver an address on surface electrochemistry at the sym­ posium on photochemical and electro­ chemical surface science on Tuesday, April 11. The Division of Analytical Chemis­ try dinner is scheduled for Tuesday, April 11, at the Butcher Shop Steakhouse, 808 Mungor Ave. The social hour begins at 6 P.M., followed by din­ ner at 7 P.M. Cost is $25. Ticket order­ ing information is available in the Feb. 13 issue of Chemical & Engineering News. The ACS Department of Continuing Education will offer a series of short courses at the meeting. For further in­ formation, see p. 366 A or contact the Department of Continuing Education, American Chemical Society, 1155 16th St., N.W., Washington, DC 20036 (202872-4508). Registration details and additional information about the meeting are available in the Jan. 16 and Feb. 13 issues of Chemical & Engineering News. The latter issue contains the fi­ nal program for the meeting. The pro­ gram that follows includes all sessions sponsored or cosponsored by the Divi­ sion of Analytical Chemistry.
