Risks of Using Additional Cabling
Introduction
Cell cables are an integral part of your potentiostat and can have a large effect on full measurement capabilities of the complete system.
Rotational Speed of Rotating Disk Electrodes
IntroductionSince the mid-20th century, rotating disk electrodes (RDEs) have been used to provide a steady stream of reactants “uniformly accessible” to the surface of a disk.
Calibration of Your Potentiostat
IntroductionAll scientific instruments must be calibrated in order to ensure proper function and accurate results, including potentiostats.
Measurement of Small Electrochemical Signals
IntroductionPotentiostats are often required to work near the limits of their measurement ability.
Care of Porous Glass Frits
IntroductionPorous glass frit is often used at the end of a reference electrode or a bridge tube to allow electrical, ionic conductivity between the bulk of the solution and the…
Understanding iR Compensation
Introduction
Some of the most common technical questions we hear at Gamry have to do with iR compensation --
Where does uncompensated iR come from?
Do I need to use iR compensation with…
The Value of Stack Mode Measurements
IntroductionSome researchers want to be able to apply or measure voltages larger than 12 V.
Understanding the Specifications of your Potentiostat
Purpose of This NoteThis technical note is intended to help you better understand the functionality and specifications of potentiostats.
Measuring the Optical Power of your LED
Purpose of This NoteWhen performing experiments with dye solar cells, light is focused on a cell and its current or voltage response is measured.
