Quality Control

Our Yttrium Carbonate Trihydrate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards suitable for technical and research applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
