Horiba Total Ionic Strength Adjustment Buffer (TISAB) for Fluoride, 500 mL (500-F-TISAB)
The Horiba Fluoride TISAB Solution (Model 500-F-TISAB) is a ready-to-use Total Ionic Strength Adjustment Buffer designed to ensure accurate and reproducible fluoride ion (F⁻) measurements when using fluoride ion-selective electrodes (ISEs). Horiba formulates this solution to stabilize ionic strength, adjust pH, and eliminate interferences during fluoride analysis.
This TISAB solution plays a critical role in fluoride measurement by maintaining constant ionic strength, buffering the sample pH, and complexing interfering metal ions such as aluminum and iron that can bind fluoride. These functions ensure that fluoride remains in its free ionic form, allowing the electrode to respond accurately and linearly.
The 500 mL bottle supports routine laboratory and field analysis in drinking water testing, environmental monitoring, wastewater analysis, and industrial quality control. The solution integrates seamlessly into fluoride ISE measurement procedures and works with compatible Horiba fluoride electrodes and ion meters.
