New in this edition are a section on determining detection limits, the general elimination of boiling point and density specifications, the use of LC in assay determinations, and a section on preparation of volumetric solutions. Twenty-four new reagents have been added. Updated methods include gas chromatography where capillary columns are now used, water determinations where coulometric methods have been added, and the replacement of flame emission techniques by atomic absorption for metal determinations. In addition, the general methods for chromatography and atomic absorption have been extensively revised to reflect their practical use in today's typical analytical laboratory. 1815 pages (1993) Clothbound ISBN 0-8412-2502-8 $149.95 O R D E R F R O American Chemical Society Distribution Office Dept. 51 1155 Sixteenth Street, NW Washington, DC 20036 Or CALL TOLL FREE

panel discussion), and Spectroscopy O n - L i n e a n d A t - L i n e Monitoring. The e n v i r o n m e n t a l m i n i - m e e t i n g featured s e s s i o n s on A t m o s p h e r i c Chemistry, Environmental Monitoring with F T - I R Spectroscopy, and the Condition of Planet Earth. Several other symposia attracted great interest among conferees, including state-of-the-art applications of step-scan FT-IR spectroscopy, a variety of techniques for the analysis of extremely complex microenvironments found within cellular subsections, new approaches to selectivity in biosensors, a chemist's perspective on industrial hygiene, immunochemistry in environmental analysis and food safety, future trends in laboratory automation and information management, and promising analytical techniques on the horizon (dedicated to the memory of L. B. "Buck" Rogers). The m e e t i n g also celebrated the 10th a n n i v e r s a r y of ICPMS with a s y m p o s i u m i n t r o d u c e d by Velmer F a s s e l , one of the p i o n e e r s of the technique and professor emeritus at Iowa State University. Five internationally known spectroscopists (Don Douglas of Sciex, Joseph Caruso of the University of Cincinnati, Gary Hieftje of Indiana University, J. W. McLaren of the N a t i o n a l Research Council of Canada, and Sam Houk of Iowa S t a t e U n i v e r s i t y ) described current research and speculated about the role ICPMS will play in the next decade. A symposium was also held to celebrate the 40th a n n i v e r s a r y of the Coblentz Society. Founded in 1953, the nonprofit organization was established to advance the discipline of molecular spectroscopy, particularly the subdiscipline of vibrational spectroscopy. Participants included Robert H a n n a h of Perkin Elmer, Peter Griffiths of the University of Idaho, Giuseppi Zerbi of Giulio N a t t a Politecnico di Milano (Italy), Curt Marcott of Procter & Gamble, and Bruce Chase of Du Pont. Looking to the future, 50 delegates from 30 countries and organizations participated in a workshop on "Analytical Chemistry in the 21st Century." The goals were to begin developing an international infrastructure that promotes and facilitates reliable measurements and to improve mechanisms for communication, cooperation, and harmonization of standards and collaboration. After contemplating future directions of analytical techniques, conferees could "boldly go where no one has gone before" by participating in

"Star Trek: Federation Science," a national traveling exhibit. This extremely popular show was the highlight of the annual social mixer arranged by the Pittsburgh Conference Committee at the Science and Technology Museum of Atlanta. The a n n u a l breakfast hosted by Centcom, Ltd., the advertising sales management company for American Chemical Society publications, featured a panel discussion on "Challenges of the Economic Recovery . . . An Agenda for C h a n g e . " S p e a k e r s included Riccardo Pigliucci, president of Perkin Elmer's i n s t r u m e n t group; William Kennedy, chairman and CEO of Analytical Technology, Inc.; and Edward White, senior vice p r e s i d e n t of the L e h m a n B r o t h e r s brokerage firm. All three s p e a k e r s observed t h a t the i n s t r u m e n t business is rapidly becoming a global industry and t h a t instrument companies m u s t try new methods if they wish to prosper in the coming years. In addition, White pointed out that t h e m a r k e t for a n a l y t i c a l i n s t r u ments is about $12 billion worldwide. The top n i n e c o m p a n i e s — P e r k i n Elmer, Hewlett Packard, Shimadzu Scientific, Thermo Instrument Systems, Waters, Hitachi, Fisons, V a r i a n , a n d J E O L — a c c o u n t for about 31% of the business, and 69% is held by 313 other companies. This fragmentation, along with the fact t h a t t h e cost of doing b u s i n e s s is high compared with that of other industries, would tend to make the analytical i n s t r u m e n t business u n a t t r a c t i v e to Wall S t r e e t . However, says White, a Lehman index of analytical i n s t r u m e n t stocks h a s risen from a b o u t 110 in e a r l y 1991 to about 170 in early 1993—an indication t h a t instrument companies are doing something right in their efforts to recover from the recent recession. Conferees also flocked to a kick-off mixer at the Georgia World Congress Center in anticipation of Pittcon '94, which will be held a t McCormick Place in Chicago. According to Richa r d Howe, 1994 p r e s i d e n t of t h e P i t t s b u r g h Conference, "The 45th Conference will be an opportunity to look back and examine where we are today in relation to how the industry and the Pittsburgh Conference started. We will have a museum in which we will showcase instruments exhibited at the first P i t t s b u r g h Conference along with key i n s t r u m e n t s developed since t h a t t i m e .
