Description

Magnesium Ion Chromatography Standard CAS NO 22537-22-0 is a high-purity reference material specifically formulated for the precise calibration and validation of ion chromatography (IC) systems. This standard is critical for ensuring accurate quantification of magnesium ions in complex sample matrices, directly addressing the need for reliable quality control and method development in analytical laboratories. It is an essential tool for scientists and technicians in industries such as pharmaceuticals, environmental monitoring, food and beverage, and water treatment, where precise ion analysis is non-negotiable.

Application

• Primary Standard for IC Calibration: Used as a certified reference material to establish calibration curves for magnesium ion detection in ion chromatography.
• Method Development and Validation: Essential for developing, optimizing, and validating new IC methods to ensure accuracy, precision, and robustness.
• Quality Control in Pharmaceuticals: Analyzes magnesium content in active pharmaceutical ingredients (APIs), excipients, and finished drug products to comply with pharmacopeial standards (USP, EP).
• Environmental Water Analysis: Quantifies magnesium hardness and ion levels in drinking water, wastewater, and natural water sources for environmental compliance and studies.
• Food and Beverage Industry: Measures mineral content, including magnesium, in beverages, dairy products, and nutritional supplements for labeling and safety.
• Clinical and Diagnostic Testing: Serves as a standard in clinical analyzers for determining magnesium levels in biological fluids like serum and urine.
• Electronic Chemicals Monitoring: Used in the semiconductor industry to analyze trace ionic contaminants, including magnesium, in ultra-pure water and process chemicals.
