Quality Control

Our Scandium Sulfate Hydrate is manufactured under controlled conditions to meet the stringent requirements of advanced material applications. Each batch undergoes rigorous analytical testing, including Inductively Coupled Plasma (ICP) analysis, to verify the 99.9% minimum purity and control trace metallic impurities. A comprehensive Certificate of Analysis (COA) detailing lot-specific results is provided with every shipment to ensure full traceability and quality assurance for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place, ideally under controlled humidity conditions. For long-term stability, store at room temperature (15-25°C) in a desiccator or an environment with low moisture content. Keep the container tightly sealed when not in use to prevent absorption of atmospheric water and carbon dioxide.
