Research, with context.
Reading a certificate of analysis
Start with the batch identifier, analytical method, report date, and identity of the testing laboratory. HPLC purity describes a measured sample — it does not by itself establish identity, sterility, or suitability for a particular use.
Check that the report corresponds to the listed batch. Look for independent laboratory contact details and verifiable accreditation rather than relying on a purity number alone.
