Quality Control

Our Tris(Methylcyclopentadienyl)Erbium is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive deposition processes. Each lot is analyzed to confirm identity, purity, and trace metal content. Certificates of Analysis (COA) detailing specific results are provided and can be tailored to meet customer-specific requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic and air-sensitive nature (easily oxidized), this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Always handle and open containers in a controlled, moisture-free environment.
