Quality Control

Our Calcium-43 is produced and handled under stringent quality protocols to ensure exceptional isotopic and chemical purity. Each batch is characterized using high-precision mass spectrometry and trace elemental analysis. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and trace metal content is provided with every shipment to guarantee consistency for your critical research and production needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material should be stored under an inert atmosphere (e.g., argon) in a cool, dry place. Recommended long-term storage temperature is 15-25°C. Handle and open containers only in a controlled, moisture-free environment to prevent oxidation and moisture absorption.
