Analysis Instruments

·         Ion-Selective Electrodes (ISEs) are high-precision analytical sensors used to selectively measure the concentration (activity) of specific ions in aqueous solutions. Designed to detect ions such as pH (H⁺), sodium (Na⁺), potassium (K⁺), calcium (Ca²⁺), chloride (Cl⁻), nitrate (NO₃⁻), fluoride (F⁻) and many others, ISEs offer a fast, direct, and accurate method of ion analysis for environmental, clinical, industrial, food, agricultural, and educational laboratories.

·         ISEs function based on the principle of electrochemical potential developed across a selective membrane that responds to a specific ion. This potential is measured against a stable reference electrode, and the output is converted into an ion concentration using Nernstian calibration.

·         These electrodes are available in combination (single-body) or separate reference + indicator electrode designs. Modern combination ISEs are easy to use, require minimal maintenance, and are compatible with most ion meters and multi-parameter analyzers.
