Reference electrodes are crucial for obtaining accurate electrochemical data, and Gamry provides reference electrodes known for their high quality and stability. Any drift in the reference electrode’s potential can lead to significant errors in both quantitative and qualitative data, far beyond simple potential measurement inaccuracies. Additionally, high-performance potentiostats may experience errors if the reference electrode’s impedance is too high or if the electrode lacks stability.
Type of Aqueous Reference Electrode:
- Saturated Calomel (Hg₂Cl₂)
- Silver/Silver Chloride (Ag/AgCl)
- Mercury/Mercurous Sulfate Reference Electrode (Hg/Hg₂SO₄)
- Mercury/ Mercury Oxide (Hg/HgO)
- Silver/ Silver Nitrate non-aqueous reference electrode (Ag/Ag+)
Applications:
- Electrochemical Research: Used in a wide range of electrochemical studies for precise and stable measurements.
- Potentiostat Calibration: Essential for calibrating potentiostats and ensuring accurate data collection.
- Battery and Fuel Cell Testing: Crucial in testing and monitoring the behavior of batteries and fuel cells over time.
