Certificate of Analysis (COA)

A document from a laboratory (ideally third-party) that certifies the identity, purity, potency, and quality of a substance. Essential for verifying research peptide quality.

"Certificate of Analysis (COA)" is filed under Quality in the PeptideAtlas glossary, alongside 12 other terms in that group.

Terms you need to read this one

HPLC (High-Performance Liquid Chromatography)

An analytical technique used to separate, identify, and quantify components in a mixture. Used in COAs to determine peptide purity percentage.

Mass Spectrometry (MS)

An analytical technique that measures the mass-to-charge ratio of molecules. Used in COAs to confirm peptide identity and molecular weight.

Endotoxin

Toxic substances (lipopolysaccharides) released from the cell walls of gram-negative bacteria. Endotoxin testing (LAL test) is important for injectable peptide quality.
