Quality Control

Our Sodium Phosphomolybdate Hydrate 99.9+% is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity specification and is free from significant impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong reducing agents.
