Quality Control

Our Tellurium Hexafluoride is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced gas chromatography (GC) and spectroscopic methods to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and other critical parameters is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed, specially passivated cylinder, protected from light and stored in a cool, well-ventilated area. Due to its gaseous, highly reactive, and oxidizing nature, cylinders must be kept upright, securely fastened, and segregated from incompatible materials such as organic compounds, strong alkalis, and reducing agents. Store at room temperature away from heat sources and open flames. Use appropriate safety cabinets or gas storage rooms designed for hazardous gases.
