IDENTITY • PURITY • QUANTITY • MICROBIAL

COA Analyzer

A certificate can contain useful evidence without answering every quality question.

COA ANALYZER

What does this test actually establish?

Mass/identity method reported

Identity answers “what appears to be present?” It is not the same as quantity.

Chromatographic purity reported

A high area-percent result does not prove total vial content.

Quantitative assay/content reported

Look for method, reference strategy and units.

Relevant microbial testing reported

Sterility, bioburden and endotoxin answer different questions.
