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.

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.

AX-2026-043327
The supplier's own declaration is printed beside the index's balance on this page. Comparing the two is the point of publishing both and rule AX-R07 is about the comparison.
AX-2026-042528
What would resolve this quickly is the batch record rather than the summary certificate — the in-process chromatogram, the fraction cut, and the reporting threshold applied. Every supplier scorecarded here holds one.
AX-2026-041273
Read the related-substances table rather than the headline. Where the table is itemised with retention times, the headline is a summary of it and the summary's precision is irrelevant.
AX-2026-043280
The certificate that arrives with a retail order is the certificate an ordinary buyer gets. Assessing it is assessing the real documentation practice rather than the sample-request one.
AX-2026-041932
The certificate field that would settle this in one line is the content basis. Anhydrous and salt-free, as-is, or gross: three different numbers and one field.
AX-2026-043484
A closed balance is what converts a purity figure into a mass. 86.49 %w/w target content on a 5 mg claim gives 4.62 mg recovered, and every step of that is on the record.
AX-2026-043474
What resolves this in one email is the batch record rather than the summary sheet: the integration report at full precision, with the reporting threshold stated. It is routinely available.
AX-2026-041216
Certificates that omit endotoxin are the majority. The documentation rubric on this site weights it at fifteen points precisely because its absence cannot be compensated by anything else on the page.
AX-2026-041919
The index publishes both figures and the arithmetic between them. It does not characterise the difference beyond stating its size, and the rule page sets out what the size does and does not support.
AX-2026-042672
A closed balance is what converts a purity figure into a mass. 88.07 %w/w target content on a 0.1 mg claim gives 0.10 mg recovered, and every step of that is on the record.
AX-2026-043659
Where a supplier declaration closes as well as the index's does, the two documents can be reconciled field by field. That is the strongest documentation outcome available.
AX-2026-043110
Provenance and documentation are independent axes. A supplier-selected sample with a complete lot-specific certificate is stronger evidence than an independently purchased one with no paperwork at all.
