Orthogonality argumentResolved
"A determination is informative in proportion to the ways it could have failed" is the general principle behind the whole orthogonality point. Worth stating explicitly as the article now does. — PrepHPLC_Pia (talk) 10:15, 8 March 2026 (UTC)
It generalises well beyond chromatography, which is why I would keep it here rather than only at the validation article. ✓ Done — Chromatokid (talk) 13:50, 8 March 2026 (UTC)
Cost of purityDone
The observation that the cost difference between 95% and 99% is not proportional to the numbers explains a great deal about pricing in this market. — CDMO_Caradoc (talk) 09:30, 6 May 2026 (UTC)
And it is why a very low price on a high stated purity is worth reading carefully — not as evidence of anything, but as a fact that has to be explained somehow. ✓ Done — CrudePeptidePearl (talk) 13:05, 6 May 2026 (UTC)
Pooling decisions
The point that pooling determines lot composition connects directly to what a lot is at Lot traceability. Worth a cross-link. — LotTraceLuka (talk) 11:20, 21 June 2026 (UTC)
Added in both directions, with the pooling sentence quoted at the traceability end so the connection survives future edits. — CrossRefCleve (talk) 14:45, 21 June 2026 (UTC)
