COA Library

The document that describes what is in the vial.

A Certificate of Analysis (COA) summarizes identity, purity, and the analytical methods used for a research compound. It is a key part of laboratory documentation and supplier transparency.

Zeptix Labs LLC provides COAs as general reference documents for catalogue materials. They support qualified research workflows and are not a substitute for your own verification when your protocol demands it.

Four fields that tell the story.

• Purity % — Numeric result from chromatography or equivalent testing.
• Method — Analytical technique (for example HPLC-UV, LC-MS).
• Laboratory — Independent testing provider and accreditation context.
• Result — Specification outcome such as PASS / FAIL against stated criteria.
