Quality Control

Our Silicon29 is produced and handled under stringent quality management protocols. Each batch is characterized for isotopic enrichment (typically >99% atom ²⁹Si) and chemical purity using advanced techniques including Isotope Ratio Mass Spectrometry (IRMS) and Glow Discharge Mass Spectrometry (GDMS). Certificates of Analysis (COA) detailing isotopic abundance, metallic impurities, and other critical parameters are provided to ensure traceability and meet the exacting standards of research and industrial applications.

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). Keep the container sealed under an inert atmosphere to minimize surface oxidation. Isolate from strong acids and strong oxidizing agents.
