Gerd M. Hermann holds a Diplom degree in physics (1967) and a Ph.D. (1971) from Justus-Liebig-Universitàt Giessen, Germany. His doctoral thesis on nonlinear and mode-crossing laser spectroscopy described the first measurements and theoretical explanations of nonlinear polarization spectroscopy. In 1975 he was appointed professor at the University Kassel, where he lectured on pure and applied physics and undertook research on fiberoptic sensors, laser spectroscopy, and atomic physics. In 1979 he joined the faculty of the University of Giessen. His interests include laser spectroscopy; Dopplerfree two-photon, two-photon excited quantum beat, and two-photon excited level-crossing spectroscopies; kyperfine structure; isotope shift; collisional processes; and analytical spectroscopy using continuum sources and lasers.

Newfangled? Old Fashioned?

HERE'snothingreallynewabouttheEG&G Princeton Applied Research Model 263. Unless you call the analog look and feel to its input knob new... Or, if you call its self-calibration feature new... Or, if you consider its moderate price new!

There's nothing old fashioned about the Model 263, either. Unless you consider the EG&G PARC reputation for quality instrumentation old fashioned. Or, the idea of software compatibility old fashioned! You won't be surprised that the new EG&G PARC Model 263 Potentiostat/Galvanostat is a 20 volt compliance, 200 m A instrument with impressive speed, precision, and sensitivity. You can use the front panel for static or scanning experiments. You can combine it with our well known software for: •

Research electrochemistry



DC corrosion measurements



Electrochemical impedance measurements

or use the free software called Headstart™to create your own experiments. If you are presently a user of an EG&G PARC software package you don't need to learn any newfangled software. The Model 263 uses the same software our other computer controlled potentiostats use. You will be amazed at the price. But a research quality instrument at a good price isn't a newfangled concept... Just an old fashioned bargain!
