MicroView
Microscope
Glassy carbon electrode in solution, coated with copper, deposited and imaged at sub-nanometerresolution.
A New Horizon in Electrochemistry
E
G&G Princeton Applied Research is pleased to open the curtain to a new horizon in re search with the MicroView Scan ning Tunneling Microscope.
The MicroView uses Scanning Tunneling Microscope (STM) tech nology, which lets you view sur faces at u p to atomic resolution. To the STM, we add a built-in potentiostat and electrochemical cell. But the MicroView gives you more than a closeup view. It electrochemically stimulates your sample in situ and measures the resulting reaction as you view a graphic image of the reaction site on your video display.
Lockhart B. Rogers is Graham Perdue Professor of Chemistry Emeritus at the University of Georgia. He has been teaching since 1942, except during February 1946-August 1948, when he was group leader of long-range re search in analytical chemistry at what is now Oak Ridge National Laborato ry. He taught for 4 years at Stanford, 13 years at MIT, 13 years at Purdue, and 12.5 years at Georgia before retir ing in 1986. Among the numerous awards he has received are the ACS awards in Analytical Chemistry and in Chromatography, the ACS Division of Analytical Chemistry Award for Ex cellence in Teaching, and the Analyti cal Chemistry Award of the Society of Analytical Chemists of Pittsburgh.
Think of the advantage of using the MicroView to monitor a graphite electrode as it deposits copper onto the surface. Or the value of examining a pit forma tion with the MicroView as it ap plies a passivation potential to iron in a chloride solution. So if you're ready for new hori zons, call us at 1-800-274-PARC. Our twenty-eight years of experi ence in electrochemistry tell us that a new day is here.
