Ammonia as N IC standard is primarily used in analytical chemistry for calibration and quality control purposes. It serves as a reference standard in ion chromatography (IC) to accurately measure and quantify ammonia concentrations in various samples. This is particularly important in environmental monitoring, where it helps assess water quality by detecting ammonia levels in rivers, lakes, and wastewater. Additionally, it is utilized in industrial applications to ensure the accuracy of ammonia measurements in processes such as fertilizer production, food and beverage manufacturing, and pharmaceutical development. Its role as a standard ensures reliable and consistent results in analytical testing.
