Horiba Ionic Strength Adjuster (ISA) for Calcium 500 mL

Horiba Ionic Strength Adjuster (ISA) for Calcium, 500 mL (500-CA-ISA)

The Horiba Calcium Ionic Strength Adjuster (ISA) (Model 500-CA-ISA) is a ready-to-use reagent designed to optimize calcium ion (Ca²⁺) measurements when using calcium ion-selective electrodes (ISEs). Horiba formulates this solution to maintain a constant ionic strength in samples and standards, ensuring accurate, stable, and reproducible calcium measurements.

By equalizing ionic strength between samples and calibration standards, this ISA minimizes activity coefficient variations that can affect electrode response. The solution also helps control potential interferences and improves electrode linearity, which is essential for precise calcium analysis across different concentration ranges.

The 500 mL bottle supports routine laboratory and field use, making it suitable for environmental monitoring, water hardness analysis, industrial process control, and research applications. The solution integrates seamlessly into calcium ISE measurement procedures and works with compatible Horiba calcium ion electrodes and meters.
