ModuLab XM ECS is a configurable electrochemistry, materials and photovoltaic measurement system.
Princeton Applied Research and Solartron Analytical provide you with a range of potentiostats, designed to fit your budget and accuracy requirements. Our potentiostats control the voltage between two electrodes and measure a resulting current. The Control Amplifier outputs power to the counter electrode (also called auxiliary electrode). A feedback loop is established to control the cell potential between the reference and working electrode. This voltage is measured by an input electrometer, which has a high impedance. This current is then measured between the working and counter electrodes while this potential is maintained at the working electrode and reference electrode.
The AMETEK SI product line includes Single Channel, MultiChannel and BiPotentiostats through both the Princeton Applied Research and Solartron Analytical brands.
A potentiostat is a device that measures the current produced by a chemical reaction at a given voltage. It maintains this voltage by sending power to an electrode called the counter electrode and measuring the resulting current between another electrode called the working electrode and a third electrode called the reference electrode. The potentiostat uses this information to calculate the cell potential between these two electrodes.
Researchers use our potentiostats to meet the most demanding scientific challenges. This includes testing new chemistries for Li-ion batteries, improving resistance to corrosion, determining concentrations of target analytes. A galvanostat is a type of potentiostat that controls the current flow between the working and counter electrodes while measuring the cell potential between the working and reference electrode.
