Quality Control

Our Vanadium Selenide 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 elemental composition, and scanning electron microscopy (SEM) for morphology. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store this material under an inert atmosphere such as argon or nitrogen for long-term preservation. Keep away from incompatible materials.
