How to read a report

A test report names the laboratory, the date of analysis, what was requested and the measured result. Purity is the share of the sample that is the named peptide; concentration is how much of it is in each millilitre. A verification key lets you confirm the report on the laboratory's site. Our article How to read a peptide certificate of analysis goes through each line.
