Quality Control

Our Umicore M73 Simes is manufactured under strict quality management systems to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes comprehensive analytical testing, including assay by ICP-OES or titration, and identification by spectroscopic methods. A Certificate of Analysis (COA) detailing purity, metal content, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent decomposition.
