ANALYTICAL CHEMISTRY Appoints Three Members to Its Instrumentation Advisory Panel ANALYTICAL
CHEMISTRY
has
ap-
pointed two new members t o its Instrumentation Advisory Panel and has reappointed one member. T h e new members are Richard A. D u r s t of t h e N a tional Bureau of Standards and Howard J. Sloane of C a r y Instruments. Jonat h a n W . Amy of P u r d u e University who has been on the Advisory Panel since its inception has been reappointed. T h e other six members who continue to assist the editors are G. Phillip Hicks, Laboratory Computing, Inc.; Charles E. Klopfenstein, University of Oregon; Donald R. Johnson, E . I. du P o n t de Nemours & Co.; M a r v i n Margoshes, Technicon Instruments Corp.; H a r r y L. Pardue, P u r d u e University; and Ralph E. Thiers, BioScience Laboratories, Inc. T h e Advisory Panel lend their expertise to the continued development of interesting and provocative editorial coverage of the interdisciplinary field of instrumentation. T h e y offer invaluable aid both in the selection of subject m a t ter and possible authors and in developing the scope and aims of the feature itself. Panel members aid in reviewing material for the feature and sometimes contribute to t h e column directly as author or coauthor. Areas of interest t o analytical chemists include not only the design of instruments, but also specific applications, such as in biomedical instrumentation, pollution measurement devices, and computer applications. The goal of the feature is to help readers broaden and deepen their knowledge in closely related disciplines so t h a t cross-fertilization of ideas might provoke original and useful thinking in the area of instrumentation for solving analytical problems. Contributions for the column often come from experts in other disciplines, such as physicists, instrument designers, or solid state specialists. Readers are invited to suggest potentially interesting topics and authors or to submit a manuscript in their own field for consideration if they feel it might be a p p r o priate to the goals of t h e feature. Brief biographical sketches and photographs of the newly appointed members to the Advisory Panel follow.
Jonathan W. Amy
R i c h a r d A. D u r s t
J o n a t h a n W . A m y was born in Delaware, Ohio, in 1923. His formal education includes a BA from Ohio Wesleyan in 1948 and M S and P h D degrees from P u r d u e University in 1950 and 1955. Since t h a t time he has remained on the chemistry department staff at P u r d u e to establish a program in chemical instrumentation. This program includes spectroscopic service laboratories, instrument construction, modification, and repair. An "instrument library" has been established for use by the department in both teaching a n d research. Consultation services are offered for both the staff and students on instrumental a n d experimental problems. Short courses have been offered on new instrumental techniques. This group has also worked closely with new staff members in establishing research programs. Special research interests have included molecular spectroscopy, gas chromatography, mass spectrometry, and data handling. D r . Amy has served as a consultant in chemical instrumentation and as a member of the board of directors of several companies and laboratories. R i c h a r d A. D u r s t is chief of the Electrochemical Analysis Section of the N B S Division of Analytical Chemistry. H e was graduated with highest honors from the University of Rhode Island (BS, 1960) and received his P h D in analytical chemistry from the Massachusetts Institute of Technology (1963). While at M I T , he was an

N S F Fellow and conducted polarographic research and electrolyte solution studies under the direction of D . N . Hume. D r . Durst was a N R C - N B S postdoctoral research associate with J . K. Taylor, visiting assistant professor at Pomona College (California), assistant professor at Boston College, and returned to N B S in 1966. His general research interests include instrumental methods of analysis with emphasis on electroanalytical techniques. Presently, he is studying the analytical applications of ion-selective electrodes. H e is t h e a u t h o r of numerous scientific articles and editor of t h e book "Ion-Selective Electrodes." D r . D u r s t is a member of t h e I U P A C Commission on Electrochemistry, the ACS, the AAAS, Sigma Xi, Phi K a p p a Phi, the Electroanalytical Group of t h e Society for Analytical Chemistry (London), and a Fellow of the Washington Academy of Sciences. H o w a r d J. S l o a n e has been director of applications research, C a r y Instruments, Monrovia, Calif., since 1967. H e received a BS in chemistry from Trini t y College (Conn.) in 1953 and earned an M A at Wesleyan University (Conn.) in 1955. After working for Dow Chemical as an infrared spectroscopist (195560) and Beckman as chief chemist (1960-67), he joined C a r y Instruments. M r .

Summer Symposium Focuses in Clinical Chemistry
Carle's M i c r o and M i n i Volume G C valves feature sandwich styled sealing. This exclusive Carle design saves you money by providing a more trouble-free G C operation. How? By preventing ghost peaks and leaks and eliminating dead volume. Successfully field proven for over eight years, the valves also have longer life. The seal is comprised of an optically flat, filled Teflon® slider between optically flat stainless steel discs. Higher reliability results because, of any geometric f o r m , optical flats make the most perfect seal possible. Comprehensive back-up data is also available exclusively from Carle. Just ask for a copy of our extensive applications guide. It w i l l take the bite o u t of specifying the right valve for your gas chromatograph. See all the latest developments in Carle valves and valving accessories at the Pittsburgh Conference. Visit us at Booth 214-216.

Cary 401. The Cary 401 Vibrating Reed Electrometer, the most accurate in the world, detects currents of 10"17 ampere, charges as small as 5 χ 10" 16 coulomb, and potentials down to 2 χ 10 - 5 volt from high impedance sources. Its standard features include solid state circuitry, multiple resistor input switching, remote input shorting, 1-second critically damped response time, and measurement of potentials from grounded sources. Modified versions offer critically damped response times of 0.5 and 2 seconds, and range changing can be computer controlled. So, if your application is in mass spectrometry, radioactivity, physical measurement or biomedical research, the Cary 401 can tackle just about any problem you've got to solve. For more information on the top vibrating reed electrometer commercially available, write Cary Instruments, a Varian subsidiary, 2724 S. Peck Road, Monrovia, California 91016.
