Quality Control

Our Germanium (II) Sulfide is produced and handled under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD), spectroscopic analysis, and elemental assay. A Certificate of Analysis (COA) detailing purity, physical characteristics, and impurity profiles is provided with each shipment to support your R&D and quality assurance protocols.

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). This material is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere such as argon or nitrogen for long-term storage to prevent oxidation and degradation.
