Product Overview
This chloride ion-selective electrode (ISE) features a sensitive membrane that generates membrane potential through ion exchange or diffusion. The sensor consists of an ion-selective membrane, internal reference electrode (Ag/AgCl), and internal reference solution. It measures electrical potential relative to a reference electrode, with the potential difference dependent on chloride ion activity in solution, enabling precise quantitative analysis.
Key Features
- Reagent-free operation eliminates pollution and reduces costs
- Redox potential measurement ensures fast response and stable signals
- Durable polypropylene construction for long service life
- High-quality sensor cables enhance signal accuracy and stability
Pre-Measurement Preparation
- Remove protective cap from electrode tip (avoid touching sensitive area)
- Shake electrode downward to remove internal air bubbles
- Activate new or long-unused electrodes by soaking in 1 ppm standard solution for at least 24 hours
- After activation, rinse with deionized water and blot dry
- Before testing, immerse electrode tip in deionized water for 5 minutes with stirring
Calibration Procedure
- Connect electrode to meter and set to mV mode
- Pour 100 mL deionized water into 150 mL beaker and stir thoroughly
- Blot electrode dry and immerse in prepared deionized water
- Add 1 mL of 1000 ppm standard solution, stir, and record stable reading (E₁)
- Add 10 mL of same standard solution, stir, and record stable reading (E₂)
- Calculate slope at 25°C as E₂ - E₁ and compare with specifications
Storage Guidelines
Short-term Storage
Preserve electrode in deionized water or low-concentration standard solution (1 ppm). No reactivation required before reuse.
Long-term Storage
Rinse with deionized water, gently wipe membrane with non-woven cloth, dry thoroughly, and store in original packaging. Reactivate in 1 mg/L standard solution, deionized water, or low-concentration solution for over 2 hours before reuse.
