Quality Control

Our Krypton-82 82Kr is produced and handled under stringent quality protocols to ensure isotopic and chemical purity. Each batch is analyzed using high-resolution mass spectrometry to verify the 99%+ minimum isotopic enrichment and the absence of significant chemical impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic abundance, purity, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed, high-pressure cylinder or container specifically designed for compressed gases, stored in a cool, well-ventilated area away from heat and ignition sources. Due to its highly volatile and gaseous nature, cylinders must be secured to prevent tipping. Protect from physical damage and direct sunlight. Store away from oxidizing agents and other incompatible materials.
