Quality Control

Our Bis(Methylcyclopentadienyl)Erbium Chloride undergoes rigorous quality testing to ensure compliance with industry standards for high-purity organometallic precursors. Each batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific test results are available upon request to support your quality assurance and R&D documentation.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; ensure containers are sealed immediately after use to minimize exposure to air and moisture.
