Quality Control

Our Ammonium Fluoroniobate 99.99% is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity specification and is free from significant contaminants. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and trace metal content is provided with each shipment to guarantee consistency and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and stored in a low-humidity environment. Keep away from strong alkalis and incompatible materials.
