Quality Control

Our Boron Trifluoride is manufactured under stringent quality management systems. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) and FTIR spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases and organic compounds. Due to its gaseous and highly reactive nature, cylinders must be kept upright, secured, and handled in accordance with all local and international hazardous material regulations. The storage area should be dry and free from ignition sources.
