Horiba Ion Standard Solution Nitrate (NO₃⁻)

Horiba Ion Standard Solution Nitrate (NO₃⁻) 100 mg/L, 500 mL (500-NO3-SL)

The Horiba 500-NO3-SL Nitrate Ion Standard Solution provides a ready-to-use calibration and verification standard for accurate determination of nitrate ions (NO₃⁻) using ion-selective electrodes and ion meters. Horiba formulates this solution to deliver a stable nitrate concentration of 100 mg/L, making it suitable for low-range nitrate calibration in laboratory and environmental applications.

This standard solution supports routine calibration, instrument performance checks, and analytical method validation for nitrate analysis in water and wastewater testing. Because the solution comes fully prepared, users can perform calibration directly without dilution, reducing handling errors and ensuring consistent measurement results.

The 500 mL bottle provides sufficient volume for repeated calibration and verification procedures. The solution fits well in environmental monitoring programs, agricultural analysis, laboratory quality control, and educational settings that require reliable low-level nitrate measurement.
