01
Confirm product and batch identity
Start by checking that the product name, specification, batch or lot reference, and document date correspond to the material under review. A document is most useful when it can be connected to the relevant supplied batch.
02
Review methods and reported results
A certificate of analysis may list analytical methods and reported results for identity, purity, appearance, or other product-specific attributes. Read each result together with its method, units, and stated specification rather than relying on a single headline value.
- Product and batch reference
- Test method
- Reported result and unit
- Document date or approval information
03
Ask focused documentation questions
If information is unclear, ask the supplier which batch the document covers and whether additional product information is available. Documentation availability can vary, so requirements should be discussed before an order is confirmed.
