About Ion Selective Electrodes

Ion Selective Electrodes Salient Features

INTRODUCTION

The concentration of Ions and gases in solution may be determined using ion selective electrodes. When a suitable sensing electrode is immersed in a solution containing ions or gases, an electrical potential may develop at the electrode surface due to a selective spontaneous reaction. The magnitude of this potential varies with the concentration of the selected ion or gas

ISEs are responsive to concentration of particular ions in the test liquid and are variable-potential electrodes.
When measurements are made using an ion meter, by calibrating with various standard solutions, direct readings of the concentration of the ion can be taken.

Slope of the electrode depends on the temperature therefore measurements must be taken at a fixed temperature.

SOLID STATE ELECTRODES are as combination electrodes complete with reference electrode. These electrodes incorporate a solid sensing surface made of compressed silver halides, or solid crystalline material.
A solid state electrode develops a voltage due to ion-exchange occurring between the sample and the inorganic membrane. An equilibrium mechanism occurs due to the very limited solubility of the membrane material in the sample.

GAS SENSORS are combination electrodes that detect dissolved gases in a solution. No external reference is required for these electrodes. The sensing element is separated from the sample solution by a gas permeable membrane

A gas sensor works due to the partial pressure of the measured gas in solution. The dissolved gas in the sample diffuses into the membrane and changes the pH in a thin film of unbuffered electrolyte on the surface of the internal pH sensor. Diffusion continues until the partial pressure of the sample and the thin film is the same. The pH change is proportional to the dissolved gas in the sample

STORAGE AND CLEANING It is sufficient to store the electrode in a standard solution during short measuring intervals. In order not to strain the membrane unnecessary, the electrode should be stored dry if it is not used for several days. After the dry storage put into standard solution for 3 - 4 hours for new measurements. Contaminations should be removed with a wet paper towel, don't use organic solvents like acetone.

Wide Compatibility and Robust Design

These ion selective electrodes are engineered for seamless connection to ion meters and standard laboratory multimeters using BNC or pin connectors. The durable glass or plastic body ensures longevity under repeated laboratory or field use. Their transparent and black coloration aids visibility during setup and operation, while the one-meter cable allows flexible positioning during sample analysis sessions.

Precise Ion Detection Across Varied Applications

Thanks to their ion-specific membranes and stable internal solutions (commonly KCl), these electrodes deliver accurate measurements for ions in water, food, pharmaceuticals, and environmental samples. The broad measurement range and quick response time provide swift and reliable data, essential for research and quality assurance processes in industries and laboratories.

FAQs of Ion Selective Electrodes:

Q: How do I use an Ion Selective Electrode for ion measurement?

A: To measure specific ions, immerse the ion selective electrode directly in the liquid sample, ensuring the membrane is fully submerged. Connect the electrode to an ion meter or laboratory multimeter (with mV capability) using either a BNC or pin connector, then follow instrument instructions to record ion concentration readings.

Q: What types of samples can be analyzed with this electrode?

A: These electrodes can measure ions in diverse samples, including laboratory solutions, drinking water, industrial effluents, food extracts, and pharmaceutical formulations. Their versatility supports use in research, environmental monitoring, quality control, and analytical testing.

Q: When should the electrode be replaced or recalibrated?

A: Electrodes typically have a shelf life of 12 to 24 months with proper storage. It is recommended to recalibrate before each measurement session, and replace the electrode if accuracy decreases or if it exceeds its shelf life.

Q: Where is the electrode commonly used in India?

A: Ion selective electrodes are widely utilized across India by dealers, distributors, exporters, importers, manufacturers, retailers, suppliers, traders, and wholesalers in laboratories, research centers, food and water testing facilities, pharmaceutical companies, and universities.

Q: What are the benefits of using an Ion Selective Electrode?

A: The main benefits include rapid response time, high specificity to target ions, low minimum sample volume requirement (25 ml), and passive operation without external power. These features enable efficient and accurate ion analysis in various scientific and industrial contexts.

Q: How does the internal filling solution affect the electrodes function?

A: The internal filling solution, such as potassium chloride (KCl) for many types, stabilizes the electrodes response and ensures reliable measurements. The choice of filling solution depends on the specific ion being detected and is essential for maintaining sensor performance.
