Reading a certificate of analysis

A short guide to the numbers that matter on a batch report — and the ones designed to distract you.

Start with the batch number

A certificate of analysis records what an independent laboratory measured in a specific batch. The batch number is the first thing to check: a certificate that does not match the product in your hand describes someone else's material.

Identity, assay, and contaminants

Then look at identity and assay — what the substance is, and how much of it is present. A purity figure such as ≥ 98.5% by HPLC is only meaningful alongside the method used to obtain it.

Finally, contaminant panels: heavy metals, residual solvents and microbiological limits. Absence of a panel is not the same as a clean result.
