| 34 | The feature that distinguishes the submitted certificates from others held by this wiki is the reproduction of the chromatogram itself. Where a certificate ordinarily reports an [[Area percent purity|area percent]] figure and asks the reader to accept it, the certificates in this set print the trace the figure was integrated from, with the gradient table, the column identifier and the detection wavelength beside it.{{r|reports}} A reader competent to read a chromatogram can therefore inspect baseline placement and integration limits rather than take the figure on trust. The limit of that is worth stating precisely: a printed trace evidences the integration of the injection it depicts. It does not establish that any particular vial was filled from the material that injection was drawn from, and no source available here bridges that gap.{{r|reports}} | 34 | The feature that distinguishes the submitted certificates from others held by this wiki is the reproduction of the chromatogram itself.

| + | 36 | [[Peptide content]] is reported separately from area percent, water is determined by [[Karl Fischer titration]] with the method named, and [[Counterion|counter-ion]] identity and content are given as a figure with its unit. Reports describe those three fields as present on issue rather than supplied on request.{{r|reports}} Together they are what allow delivered peptide mass to be calculated from the fill; separately, none of them is sufficient. | |
