Quality Control

Every batch of our analytical standards is produced and verified under strict quality management protocols. The concentration is precisely confirmed using calibrated, traceable methods against certified reference materials. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the exact concentration, purity, solvent verification, and analytical method data (typically GC-MS or HPLC). Our quality system ensures compliance with relevant guidelines for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). The product is supplied in a strong acid/organic solvent and is light-sensitive (store away from light). Allow the solution to reach room temperature before opening to prevent condensation. For long-term stability, storage under inert atmosphere (e.g., argon) is recommended.
