Cerium standard is widely used in analytical chemistry as a reference material for calibrating instruments and validating methods, particularly in inductively coupled plasma (ICP) and atomic absorption spectroscopy (AAS). It ensures accurate measurement of cerium concentrations in environmental, industrial, and geological samples. In the glass and ceramics industry, it serves as a benchmark for quality control, ensuring the desired optical and mechanical properties of products. Additionally, it plays a role in catalysis research, helping optimize cerium-based catalysts for applications like automotive exhaust systems and chemical synthesis. Its use in metallurgy ensures precise alloy formulations, enhancing material performance.
