Reading a certificate of analysis
The COA identifies the product, catalog number and lot number; lists the specification for each test alongside the measured result; and is dated. Where available, chromatograms and spectra are attached.
Lot traceability
Lot numbers are printed on every vial label and packing slip and recorded against each order line, linking the shipped material to its lot documentation.
