1.3. Software
The PARSTAT 4000 is fully compatible with the VersaStudio software only. The
PARSTAT 4000 will not operate with any other software other than that specified in this
manual or the most recent documentation available on the web site
(http://www.princetonappliedresearch.com). Likewise, the PARSTAT 4000 does not have an
open command set to allow user programming outside of the VersaStudio software.
The software is designed specifically to work with Windows XP, Windows 7 and Windows
8, but it is highly recommended that Windows XP or Windows 7 be used.
1.4. Polarity Convention
The PARSTAT 4000 hardware follows the American polarity convention. (Positive current
is cathodic; that is, a current is defined as positive if reduction is taking place at the
working electrode. Negative current is anodic; that is, a current is defined as negative if
oxidation is taking place at the working electrode. If the working electrode is driven
positive with respect to the equilibrium potential, the resulting current is anodic. If the
electrode is driven negative with respect to the equilibrium potential, the resulting current
is cathodic.)
In complex electrochemical systems, there might be more than one equilibrium system.
Where this is the case, either polarity with respect to the equilibrium potential could give
rise to anodic or cathodic current, according to the systems’ characteristics.
