Precise Potassium Measurement for Laboratories

Engineered for accuracy and reliability, the Metrohm Combined polymer membrane electrode enables precise measurement of potassium ion concentrations. Its compatibility with Metrohm ion meters and titrators makes it highly suitable for laboratory environments where rigorous quality control is essential. Its straightforward operation and rapid response empower scientists and technicians to obtain results efficiently.

User-friendly Design and Long-lasting Performance

This electrode is designed for ease of use with a standard BNC connector and a robust, transparent/black PVC housing. With a recommended storage in potassium chloride solution at room temperature and a shelf life of approximately 12 months, it ensures consistent performance over time. Its passive operation requires no power, reducing maintenance and operational complexity.

FAQ's of Metrohm Combined polymer membrane electrode, K:

Q: How do I correctly use the Metrohm Combined polymer membrane electrode for potassium measurements?

A: Immerse the electrode directly into a solution containing at least 10 mL volume, ensuring it is connected to a compatible Metrohm ion meter or titrator. Measure the potential in mV, which is then used to determine the potassium ion concentration via calibration.

Q: What is the recommended process for storing the electrode when not in use?

A: The electrode should be stored in a potassium chloride solution at room temperature. Proper storage helps maintain membrane integrity and extends the shelf life to approximately 12 months.

Q: When should I replace my potassium ion-selective electrode?

A: Electrode replacement is recommended after about 12 months of use, or sooner if calibration drift, slow response times, or inconsistent readings occur, as these indicate membrane degradation.

Q: Where can this electrode be used in laboratory applications?

A: This potassium-selective electrode is ideal for use in analytical chemistry labs, quality control settings, and for educational purposes, where precise measurement of potassium concentrations in solutions is required.

Q: What are the benefits of using this combined polymer membrane electrode over traditional methods?

A: This electrode delivers fast and reproducible results, with a response time under 30 seconds and reproducibility below 2% RSD. Its simple operation, low maintenance, and compatibility with standard Metrohm equipment optimize laboratory workflow and reliability.

Q: Is any calibration required before using the electrode?

A: Yes, calibration with standard potassium solutions within the measuring range (1 105 to 1 mol/L K+) is essential before each measurement series to ensure accuracy and reproducibility of results.
