Topic starter   [#10332]

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-10321.

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

A chromatographic peak-area figure and net material content answer different questions. Record the report’s own definition and units before comparing it with another percentage.

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.

The index should list supplied evidence and missing evidence separately. Use method-specific wording rather than a blanket verified or safe label.
