Quality Control

Our Magnesium Potassium Orthophosphate is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for food, pharmaceutical, and industrial applications. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, heavy metal content, and loss on drying. Specifications can be aligned with FCC, USP, or other relevant pharmacopoeial standards based on customer requirements.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
