Quality Control

Our Dihydrogen Sulfide-D1 is produced and handled under stringent conditions to ensure isotopic purity and chemical integrity. Each batch is characterized using advanced spectroscopic and chromatographic techniques, including NMR and GC-MS, to confirm isotopic enrichment and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (e.g., atom % D), chemical purity, and gas composition is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed, specially designed cylinder or container suitable for pressurized gases, protected from light. Store in a cool, well-ventilated area away from direct heat sources and incompatible materials such as strong oxidizers. Due to its highly volatile and gaseous nature, ensure containers are securely fastened and storage areas are equipped with appropriate gas detection and ventilation systems. Handle and store in accordance with all local and international regulations for compressed and toxic gases.
