Custody from checkout to injection is documented on this record. Provenance plus custody is what makes a single result generalise past the vial it came from.

Section 2
Records submitted
A submitter chose to buy this material and to pay for this assay. That choice is the selection mechanism behind the whole index and it is not random.
Section 3
Annotations
Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.
Direct despatch means the submitter never held the vial. That is a cleaner custody chain and a weaker selection story, simultaneously.
Purity 99.38 %, water 1.70 %, counter-ion 4.98 % acetate, mass balance closed, provenance independent. There is nothing outstanding on this record.
Purity 97.67 %, water 6.08 %, counter-ion 0.00 % counter-ion, mass balance closed, provenance independent. There is nothing outstanding on this record.
Purity 98.92 %, water 9.48 %, counter-ion 8.35 % acetate, mass balance closed, provenance independent. There is nothing outstanding on this record.
A retail vial at 98.29 % is worth more evidentially than a selected vial at a higher figure. That is the whole argument for recording provenance at all.
Every headline figure on the corresponding scorecard survives restriction to buyer-sourced records. That sensitivity analysis is published on the scorecard and it is the reason this record can be included at all.
Ordering under an unremarkable name and address is the whole method. It requires no cooperation from anybody and it produces the strongest evidence this index holds.
Independently purchased, at the submitter's own cost, forwarded without the supplier's involvement. That is the definition and this record meets it.
Custody is documented and continuous here, which is more than most records have. The weakness on this one is selection, not handling.
The index cannot verify that the vial assayed is representative of the lot it came from, and says so on every record. Provenance narrows that gap; it does not close it.
