Horiba Ion Standard Solution Ammonium (NH₄⁺)

Horiba Ion Standard Solution Ammonium (NH₄⁺) 100 mg/L, 500 mL (500-NH4-SL)

The Horiba Ammonium Ion Standard Solution 100 mg/L (Model 500-NH4-SL) provides a ready-to-use calibration and verification standard for accurate measurement of ammonium ions (NH₄⁺) using ion-selective electrodes and ion meters. Horiba formulates this solution to deliver a stable ammonium concentration of 100 mg/L, supporting precise calibration at lower concentration ranges commonly used in environmental and laboratory analysis.

This standard solution enables reliable calibration, performance checks, and method validation for ammonium measurements in water and wastewater testing. Because the solution comes fully prepared, users can perform calibration immediately without dilution, which reduces handling errors and improves measurement consistency.

The 500 mL bottle supplies sufficient volume for repeated calibration and verification procedures. The solution suits routine use in environmental monitoring, industrial quality control, research laboratories, and educational settings where accurate low-level ammonium determination is required.
