Quality Control

Our Oleic-13C18 Acid is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity, which is critical for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity (by GC or HPLC), and identity confirmation (by NMR and/or IR). We adhere to relevant industry standards for high-purity reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. For long-term stability, keep the material in a cool, dry place away from heat and incompatible substances.
