TermDefinition
Batch traceabilityLot traceabilityThe linkage between a certificate and the specific batch supplied, by batch identifier and date. A certificate that cannot be linked to the material in hand is a specimen document.
Certificate of analysisCOAThe document accompanying a batch, reporting the determinations made and the results obtained. Its value depends entirely on which fields it carries and whether the methods are named.
Good manufacturing practiceGMP · cGMPA regulated system of controls over manufacture, in which a claim of compliance is meaningful only where an inspecting authority is named. An unverified compliance claim is a marketing statement.
ISO 17025The international standard for the competence of testing laboratories. Accreditation is granted for named tests within a defined scope; a laboratory accredited for one determination is not thereby accredited for another.
Minimum data standardThe Institute’s specification of the fields a certificate must carry for a purity or content claim to be interpretable. Fields are classified as critical or recommended; a certificate missing a critical field cannot support the corresponding claim.
Not assessedIn an Institute supplier dossier, an attribute the Institute did not examine. Carries no implication about the attribute and is recorded so that a reader can distinguish it from a failed verification.
Not verifiedIn an Institute supplier dossier, a claim for which the Institute has looked for supporting documentation and not found it. Distinct from not assessed.
Research use onlyRUOA supply designation indicating that material is not manufactured under a marketing authorisation and is not approved for human or veterinary use in any jurisdiction. A designation about regulatory status and not a statement about quality.
Sample provenanceThe record of where an analysed sample came from and who selected it. A supplier-selected sample and an independently purchased one are different classes of evidence and the Institute labels them as such.
Third-party testingAnalysis performed by a laboratory independent of the supplier. Stronger evidence than a supplier-issued certificate, and weaker than analysis of an independently purchased sample, because the supplier chose which material to submit.
VerifiedIn an Institute supplier dossier, a determination supported by documentation the Institute has examined. Verification is of the documentation and never of the product, which the Institute has not tested.
Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective. The Institute publishes certainty ratings and never recommendations. No telephone number, messaging handle or ordering channel appears anywhere on this site.
