Topic starter   [#13596]

A reagent dossier contains a summary purity percentage but not the method or underlying trace. The draft index calls it fully verified. Which parts of that label can actually be supported?

Discussion record: RESEARCH-13585.

Separate document provenance, identity, purity and the conditions measured. A percentage without its method and sample linkage cannot establish all of those claims.

Ask whether the sample identifier, issuing laboratory, report date and relevant analytical method can be verified. A copied certificate may be genuine as a document while its relationship to the sample remains unestablished.
