Ammonia as N IC Standard is primarily used in analytical chemistry for calibration and quality control purposes. It serves as a reference material in ion chromatography (IC) to ensure accurate measurement and detection of nitrogen-containing compounds in various samples. This standard is essential in environmental testing, where it helps monitor ammonia levels in water, soil, and air, ensuring compliance with regulatory standards. Additionally, it is utilized in industrial applications to verify the performance of analytical instruments and maintain consistency in testing procedures. Its precise concentration and stability make it a reliable tool for researchers and laboratories focused on accurate nitrogen analysis.
