MODULE SUMMARY

The modules which can be fitted to the chassis are as follows:
• The potentiostat is the basic component of the ModuLab XM system that, on
its own, is able to perform DC electrochemical experiments on a wide range
of batteries, fuel cells and electrochemical cells. Optional auxiliary voltage
measurement channels may be added to the potentiostat to provide additional
voltage measurements of parts of the cell.
• High voltage optional modules are available to extend the voltage range of
the potentiostat to either ±30V or ±100V as preferred. The high voltage
options are used, for example, for testing multi-cell batteries, fuel cells or for
organic electrochemistry applications.
• A femto ammeter may be added to the system, operating with the basic
potentiostat or in combination with the high voltage option plus potentiostat.
This extends the current measurement resolution to the measurement of very
high resistance cells, for use with microelectrode studies, anti-corrosion
coatings and other corrosion applications.
• An internal power booster may be added to provide the capability for testing
higher power batteries and fuel cells and also for use in electroplating
applications. The high voltage option can be used together with the internal
booster to provide high voltage measurements from parts of the cell using its
auxiliary voltage inputs.
• A DSSC option is also available to allow control of an optical bench for
testing Dye Sensitized Solar Cells. Refer to Solartron Analytical website for
more details.
• A frequency response analyzer may also be added to the system to provide
high-speed impedance measurements using any of the above combinations of
equipment. Impedance of parts of the cell may also be measured using the
auxiliary inputs option on the main potentiostat or the high voltage option as
preferred. The FRA is fully integrated into the system, allowing impedance
measurements of extremely high impedance or low impedance cells
depending on the optional modules that are fitted.
The following module can be installed external to the chassis:
• An external power booster may be used for applications that exceed the
capacity of the internal booster. The external booster is placed in the circuit
between the potentiostat and the cell, so that it amplifies and attenuates the
signals using fixed scaling factors. The voltage output from the potentiostat
to the cell is multiplied by 10, and the current return from the cell to the
potentiostat is divided by 1000. The result is that the potentiostat "sees" a
smaller load, but the ModuLab XM software interprets the data to take
account of the scaling factors.
The high voltage module can be used together with the external booster to
provide high voltage measurements from parts of the cell using its auxiliary
voltage inputs.
