Results

Measured against the index acceptance specification for the non-peptide adjuncts class. A specification is a decision the index made; a result is a measurement. See where each threshold came from.

Chromatogram and peak integration

The figure is drawn from the table. It is not an independent illustration — if a number in the table changed, the trace would change with it.

Figure 1. RP-HPLC trace, 30 min gradient, 214 nm. Drawn from the peak-integration table below: peak positions are the reported retention times, peak areas are the reported area percentages, peak widths follow the reported plate count of 55,147, and skew follows the reported asymmetry factor of 1.12. Baseline noise is seeded from the report ID and is illustrative. The lower panel is the same trace at a stated vertical expansion with the slow gradient drift subtracted, because at full scale a 0.24 % impurity against a 99.44 % main peak is a line two pixels tall; the main peak runs off-scale there by design.

Reporting threshold 0.05 % area. Peaks below it are not reported and are therefore excluded from the total, which overstates purity by their sum — see peak integration.

Section 4

Gravimetric mass balance

Water, counter-ion, residual and total peptide content are exhaustive and mutually exclusive categories. They must account for 100 % of the cake mass. The index closes this to within 0.02 pp and the build asserts it.

Where a sample came from changes the weight of the evidence. The index treats it as a first-class field.

Annotations 4

Signed technical comments from index contributors. Not a discussion forum — annotations question or contextualise the result, and the data team replies where a reply is warranted.

wide_iqr
A single result at 99.44 % is one draw. What makes a supplier's process legible is the spread across its lots, and that is on the scorecard rather than here. This record is one good point in a distribution worth reading whole.
sample_vs_retail
Where a supplier-supplied result on the same lot also exists, the pair is the informative object rather than either record alone. The batch page shows whether one does.
moq_reality
Retail purchases test the retail channel. Manufacturer-tier material bought at kilogram scale is a different product with different documentation, and this index sees very little of it.
RT_shift
Escalation on this rule means the index looks for a mass to resolve the question. Where a mass exists and agrees, the flag is recorded as a method note and the record stands.
