Say Goodbye to Either/Or Electrochemistry
Square Wave Stripping 80 ppb Lead Mercury Microelectrode
ost electrochemical software is designed to do either sophisti cated research or routine measure ments. 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 electro chemistry. The Model 270 Electro chemical 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) • Automatic control of both the PARC Model 303A SMDE and a se lection 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-break ing research one day and routine measurements the next, say hello to total electrochemistry.
