| 61 | Why the counter-ion figure matters is worth stating once, because a reader who does not already know cannot see why the submitted set treats it as significant. Chromatographic purity expresses the proportion of the material that eluted which was the target peptide. It says nothing about how much peptide is in the vial, because the counter-ion is not peptide and carries mass. On a trifluoroacetate salt the difference runs to several per cent, so a certificate that omits the figure leaves a reader unable to convert a stated fill into a quantity of peptide.{{r|reports}} | 61 | Why the counter-ion figure matters is worth stating once, because a reader who does not already know cannot see why the submitted set treats it as significant.

| + | 63 | One submission carries more weight than the rest and is recorded separately for that reason. A catalogue line purchased in 2025 was purchased again eleven months later, and both lots were determined on the same stated method; the two results differ by a tenth of a percentage point.{{r|reports}} Agreement of that kind is a stronger finding than agreement between two laboratories on one sample, because it speaks to a process holding over an interval rather than to two measurements of one object. It is still a finding about two lots and not about a catalogue. | |

| + | 68 | Catalogue lines dispatch from held stock, and the organisation's own material states a two-working-day dispatch window on listed items.{{r|selfpub}} Regional stock is described as held forward for the most frequently ordered lines, with the remainder dispatched from Changzhou; submissions describe a difference of several days between the two and recommend establishing which applies before ordering.{{r|reports}} Bulk raw-material quantities and custom synthesis are quoted individually with a timeline stated on the quotation, and submissions describe delivery at or inside that date.{{r|reports}} Submissions also describe the quotation itself taking about three working days to arrive on custom work, which is an interval a reader planning a schedule should budget for separately, since it precedes the stated timeline rather than being contained by it.{{r|reports}} | |
