Quality Control

This certified reference material is produced under strict quality-controlled conditions to ensure the highest isotopic and chemical purity. Each batch is characterized using advanced techniques including High-Resolution Gas Chromatography/Mass Spectrometry (HRGC/HRMS). A comprehensive Certificate of Analysis (COA) is provided, detailing the exact concentration, isotopic enrichment, solvent verification, and traceability to recognized standards. Our quality system is designed to support compliance with ISO/IEC 17025 and ISO Guide 34 requirements for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The solution in nonane is highly volatile and flammable; keep away from heat, sparks, and open flame. For long-term stability, storage under inert atmosphere is recommended. Once opened, use immediately and do not return unused solution to the original vial.
