Horiba Ionic Strength Adjuster (ISA) for Nitrate 500 mL

Horiba Ionic Strength Adjuster (ISA) for Nitrate, 500 mL (500-NO3-ISA)

The Horiba Nitrate Ionic Strength Adjuster (ISA) (Model 500-NO3-ISA) is a ready-to-use reagent designed to ensure accurate and reproducible nitrate ion (NO₃⁻) measurements when using nitrate ion-selective electrodes (ISEs). Horiba formulates this solution to maintain a constant ionic strength in samples and calibration standards, which is essential for reliable nitrate analysis.

By equalizing ionic strength, this ISA minimizes variations in ion activity that can affect electrode response. It helps improve measurement linearity, stability, and repeatability across different sample matrices. The solution integrates directly into standard nitrate ISE measurement procedures and supports consistent analytical results.

The 500 mL bottle suits routine laboratory and field applications, including environmental monitoring, water and wastewater testing, agricultural analysis, and industrial quality control. The solution works seamlessly with Horiba nitrate ion-selective electrodes and compatible ion meters.
