>>Overview
The core theory of pH electrode measurement is the Nernst equation. The sensor used in potentiometric analysis is called a galvanic cell. A galvanic cell is a system that converts chemical reaction energy into electrical energy. The voltage of this cell is referred to as the electromotive force (EMF). This EMF consists of two half-cells. One half-cell is the measuring sensor, whose potential is related to the activity of specific ions; the other is the reference half-cell, often called the reference sensor, which is typically connected to the measurement solution and the instrument.
>>Electrode Maintenance and Care
○ Before use, unscrew the protective cap and immerse the electrode bulb and liquid junction in the sample.
○ If salt crystals form near the electrode tip or inside the cap due to electrolyte evaporation, rinse with water. This indicates normal dialysis membrane function.
○ Check for air bubbles in the glass bulb by shaking the electrode vertically.
○ Keep the glass membrane hydrated for fast response. After measurement or calibration: Rinse the electrode thoroughly. Add storage solution (3 mol/L KCl) to the protective cap.
○ Ensure terminal connections remain dry. Clean with anhydrous alcohol if contaminated.
○ Avoid prolonged immersion in distilled water, protein solutions, or contact with silicone grease.
○ For aged electrodes with cloudy membranes or deposits, soak in 10% HCl, then rinse.
○ Regularly clean and calibrate the electrode. If calibration fails after maintenance, replace the electrode.
>>Lifespan
Under normal conditions with proper maintenance, electrodes last over 12 months. Even unused electrodes have a shelf life of 12–24 months (if stored correctly). Exposure to strong acids, bases, high temperatures, or corrosive liquids shortens lifespan. Electrodes are consumables and generally not covered by warranty.
>>Electrode Calibration
○ Use fresh pH/ORP standard buffer solutions of appropriate concentrations.
○ Remove the protective cap and rinse the electrode with distilled water.
○ Set the instrument to calibration mode (refer to the instrument manual for details).
○ After calibration, measure actual samples.
