Thermo Scientific™ Orion™ TISAB II for Fluoride Electrode

Thermo Scientific™ Orion™ TISAB II is a high-performance Total Ionic Strength Adjustment Buffer (TISAB) formulated to optimize the accuracy and stability of fluoride ion (F⁻) measurements performed with fluoride ion-selective electrodes (ISEs). This ready-to-use solution maintains constant ionic strength and pH while effectively eliminating interference from polyvalent metal ions such as aluminum (Al³⁺) and iron (Fe³⁺) that could otherwise form complexes with fluoride ions and skew measurement results.

By suppressing ion interactions that interfere with electrode response, TISAB II ensures consistent calibration curves and reproducible results across a wide variety of sample types, making it a standard reagent in environmental monitoring, industrial process control, food quality testing, and analytical research.
