Quality Control

Our Cesium Dihydrogen Phosphate is manufactured under controlled conditions to ensure high purity and batch-to-batch consistency. Quality is verified through a suite of analytical techniques including titration, ICP-OES, and X-ray diffraction. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment. We support compliance with relevant industry standards and can tailor specifications to meet specific research or production requirements.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
