Horiba Ionic Strength Adjuster (ISA) for Potassium, 500 mL (500-K-ISA)
The Horiba Potassium Ionic Strength Adjuster (ISA) (Model 500-K-ISA) is a ready-to-use reagent designed to ensure accurate and reproducible potassium ion (K⁺) measurements when using potassium ion-selective electrodes (ISEs). Horiba formulates this solution to maintain a constant ionic strength in both samples and calibration standards, which is essential for stable and linear electrode response.
By equalizing ionic strength, this ISA minimizes variations in ion activity that can otherwise introduce measurement errors. It improves measurement accuracy, repeatability, and response stability across different sample matrices. The solution integrates directly into standard potassium ISE measurement procedures and supports consistent analytical results.
The 500 mL bottle supports routine laboratory and field applications, including water quality monitoring, agricultural analysis, industrial process control, and research laboratories. The solution works seamlessly with Horiba potassium ion-selective electrodes and compatible ion meters.
