Product Overview
The ion-selective electrode (ISE) features a sensitive membrane that generates membrane potential through ion exchange or diffusion. Comprising an ion-selective membrane, internal reference electrode (typically Ag/AgCl), and internal reference solution, this electrode measures electrical potential of specific ions in solution relative to a reference electrode with constant potential. The potential difference depends on ion activity, which relates to concentration for quantitative analysis.
Key Features
- Reagent-free operation eliminates pollution and reduces costs
- Redox potential measurement ensures fast response and stable signals
- Durable PP (polypropylene) electrode construction
- High-quality sensor-specific cables enhance accuracy and stability
Pre-Measurement Preparation
1. Remove protective cap from electrode tip
2. Shake electrode downward to remove internal air bubbles
3. For new or unused electrodes: activate by soaking in 1 ppm standard solution for at least 24 hours
4. After activation: rinse with deionized water, blot dry, then immerse in deionized water for 5 minutes with stirring
Avoid touching the sensitive membrane area with fingers to prevent contamination
Calibration Procedure
1. Connect electrode to meter and set to mV mode
2. Pour 100 mL deionized water into 150 mL beaker and stir thoroughly
3. Immerse rinsed and dried electrode in deionized water
4. Add 1 mL of 1000 ppm standard solution, stir, record stable reading (E₁)
5. Add 10 mL of same standard solution, stir, record stable reading (E₂)
6. Calculate slope at 25°C as E₂ - E₁ and compare with specifications
Troubleshooting & Storage
Troubleshooting: If slope deviates, prepare fresh diluted standard solution, soak electrode for 10 minutes, and recalibrate. Contact technical support if issues persist.
Short-term Storage: Preserve in deionized water or low-concentration standard solution (1 ppm)
Long-term Storage: Rinse with deionized water, wipe membrane, dry thoroughly, and store in original packaging
