Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized to confirm identity, purity, and performance suitability for catalyst applications. Certificates of Analysis (COA) detailing key parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers should be handled under an inert atmosphere (argon or nitrogen) and sealed immediately after use to prevent decomposition.
