Quality Control

Our Metaphosphate is produced under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for assay, phosphate content, and impurity levels. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with relevant industrial and food-grade (FCC) standards where applicable. We support our clients' audit and regulatory needs with comprehensive documentation.

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 when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
