Rollups

Supplier scorecards

20 suppliers, 6,722 reports, 1,154 batches. Each scorecard is arithmetic over the records the index holds for that supplier — median purity and its interquartile range, reproducibility across repeat tests of one lot, divergence between the supplier's own certificate and independent measurement, documentation completeness, and the provenance mix of the samples tested.

Read this table the way the data allows

Aggregates on this page are computed over the records the index holds, which are not a random sample of the material on the market. Lots that get tested are lots someone chose to test. Read every figure here as a description of this dataset rather than as an estimate of a population.

Two further constraints on this table specifically. First, purity barely discriminates: nineteen of 20 supplier medians fall inside a 1.5 pp band, which is not much wider than the disagreement between two laboratories testing the same vial. Second, coverage is wildly uneven — from 10 records to 575 — so the confidence attached to each row differs by more than the rows differ from each other. The columns that actually separate these suppliers are recovered mass per vial, documentation and reproducibility, and they are on the comparison page.

Figure. Purity distribution per supplier, ordered by coverage. Box spans Q1–Q3, heavy rule is the median, whiskers are the extreme observations inside 1.5 IQR, and points beyond the fences are drawn individually. The vertical line is the index median, 98.99 % area. Read the widths before the positions: the boxes overlap almost completely, and the suppliers that separate do so by having longer left tails rather than lower medians.

Block 4

Suppliers without a scorecard

Named in the trade and, in most cases, in this index’s own submission queue — but below the coverage at which any statistic here would mean anything.

A scorecard needs enough records to compute a median, a spread and a divergence figure that are not noise. The 188 suppliers below have not reached it. They are listed so the 20 above read as a coverage threshold rather than a shortlist. No scorecard, no rating, no outbound link.
