Quality Control

Our Tris(Butylcyclopentadienyl)Erbium is produced under stringent conditions to ensure batch-to-batch consistency and high purity, critical for sensitive applications like thin-film deposition. Each lot undergoes comprehensive analysis, including NMR spectroscopy and elemental analysis (CHN), to confirm identity and composition. A detailed Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to support your quality assurance protocols.

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 moisture-sensitive and easily oxidized; exposure to air or humidity must be minimized to preserve stability and performance. Keep away from strong acids and oxidizing agents.
