A Certificate of Analysis (COA) records the analytical results for an identified batch of material. A useful report ties its results to a product identifier, batch number, test date and testing laboratory.
Purity is method-dependent. High-performance liquid chromatography (HPLC) can describe chromatographic purity, while mass spectrometry can support identity assessment. Review the full analytical report when selecting materials for an experiment.
Always match the batch on the material to the batch in the report. Review the methodology, reported units and original document before drawing conclusions. Find available batch reports in the PEPT&CO COA library.
