Quality Control

Our Cd3S is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, and particle size distribution (PSD) measurement. A Certificate of Analysis (COA) detailing purity, heavy metal content, and physical specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and potential reactivity with strong alkalis and organic solvents, keep the container tightly sealed when not in use and store separately from incompatible materials.
