Say Goodbye to Either/Or Electrochemistry

Square Wave Stripping 80 ppb Lead Mercury Microelectrode

Mercedes de Frutos received her B.S. degree (1980) and her M.S. degree (1983) in chemistry from Autonoma University (Madrid, Spain). Her Ph.D. thesis (1989) focused on high-performance chromatographic techniques for the analysis of dairy products and was performed at the Consejo Superior de Investigaciones Cientificas (Madrid, Spain). For the past two years she has been a Fulbright scholar in the chemistry department at Purdue University under the direction of Fred E. Régnier. Her current work focuses on the development of immunochromatographic techniques and their applications.

ost electrochemical software is designed to do either sophisticated research or routine measurements. In the past, if your lab did both, you were stuck.

Either you had to buy two separate packages, which meant satisfying the compatibility requirements for both and learning two very different environments. Or you had to buy one package and make do. Well say goodbye to either/or electrochemistry. The Model 270 Electrochemical Analysis software from EG&G Princeton Applied Research is unmatched on all counts—power, versatility, and ease of use. Consider just this small selection of Model 270 advantages: • Both time-tested hardware (Model 273 Potentiostat) and state-of-theart computer environment (IBM platform, pull-down menus)

Fred E. Régnier has been professor of chemistry at Purdue University since 1990. After completing a Ph.D. at Oklahoma State University (1965) and postdoctoral work at the University of Chicago (1967) and Harvard University (1969), he became assistant professor of biochemistry at Purdue (1969). During 20 years in the Biochemistry Department at that institution, he served as associate professor (1971-76), professor (1976-90), and associate director of the Agricultural Experiment Station (1976-78). He is the author of 150 publications and 15 patents on various aspects of chemistry, biochemistry, and separation techniques and their application to proteins. A recipient of the Dal Nogare Award for Achievements in Chromatography in 1987 and the ACS Award in Chromatography in 1989, he continues to pursue his interest in the rapid separation of proteins in both the analytical and preparative modes.

• Automatic control of both the PARC Model 303A SMDE and a selection of microelectrodes • Traditional voltammetry/polarography and fast Square Wave • Easy-to-learn Standard Mode for routine use and feature-rich Expert Mode for finer experimental control So if you typically do ground-breaking research one day and routine measurements the next, say hello to total electrochemistry.
