Quality Control

Our Cesium Aluminum Orthosilicate -100 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including X-ray diffraction (XRD) for phase purity and inductively coupled plasma optical emission spectrometry (ICP-OES) for elemental assay and impurity profiling. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications to ensure compliance with your project requirements and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 and carbon dioxide, which may affect performance.
