Quality Control

Our Erionite is sourced and processed under stringent quality protocols to ensure batch-to-batch consistency and purity for research and industrial applications. Material identity is confirmed via X-ray diffraction (XRD) and morphological analysis. We provide comprehensive Certificates of Analysis (COA) detailing chemical composition, crystalline phase, and fiber morphology data upon request, supporting compliance with relevant material safety standards.

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). As a fine fibrous powder, it is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent moisture absorption and caking. Store away from incompatible materials such as strong acids.
