Understanding quality, laboratory documentation and transparency.
When sourcing research products, the documentation behind each batch matters as much as the product itself. This guide explains what quality documentation is, how common laboratory tests work, and what to look for when reviewing a supplier's batch information.
Reliable research depends on knowing exactly what you are working with. Clear documentation allows researchers to confirm a product's identity, check its measured purity and trace it back to a specific production batch. Without it, results can be difficult to reproduce or verify.
A Certificate of Analysis is a document issued for a specific batch that records the results of laboratory testing. A well-presented CoA typically includes:
The batch number on the CoA should match the batch number printed on the product label.
HPLC separates the components of a sample so that the main compound can be measured against any impurities. It is the method most commonly used to report a purity percentage.
Mass spectrometry measures the molecular mass of a compound. It is used to confirm identity, showing that the material tested is the compound it is labelled as.
Used together, HPLC and mass spectrometry give a clearer picture than either method alone: one indicates how pure a sample is, the other confirms what it is.
Every production run is assigned a batch number. This links each product to its own test results, so documentation always refers to the material actually supplied rather than a generic example. If you have a question about a product, quoting the batch number allows its records to be located quickly.
Independent testing is carried out by a third-party laboratory that is separate from the supplier. This provides an additional, impartial check on identity and purity, and adds confidence that published results are objective.
Correct storage helps a product remain consistent with its documented specification. Always follow the storage guidance provided with the product, keep containers sealed until use, and store away from heat, moisture and direct light.

Check that the batch number on the certificate matches the batch number on your product label.
It shows the proportion of the main compound detected in the tested sample, usually measured by HPLC. The remainder represents other components detected during analysis.
