Quality Control

Our Lanthanum(III) Telluride is produced and handled under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, which may include X-ray diffraction (XRD) for phase identification, inductively coupled plasma (ICP) analysis for metallic impurity profiling, and particle size analysis. A Certificate of Analysis (COA) detailing the specific results is provided with every shipment to guarantee compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation and degradation. Keep away from strong acids and strong oxidizing agents.
