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-2026-042004
Ask for the chromatogram. In every case the index has followed up, one existed, and it carried the unrounded figure.
AX-2026-043009
The declared figure for MKM-2602-X4844 and the independent median differ by less than the inter-lab limits of agreement. That is the comparison that matters and the rounding does not change it.
AX-2026-042560
The certificate for lot HJ-2605-D6191 states purity as a round figure. Integrated areas do not land on halves, so this is either a rounded presentation of a real integration or a release specification carried into the result field. Independent measurement here is 98.60 %, which is consistent with either.
AX-2026-042951
The declared figure for MKM-2512-B3991 and the independent median differ by less than the inter-lab limits of agreement. That is the comparison that matters and the rounding does not change it.
AX-2026-042562
The declared figure for HJ-2605-D6191 and the independent median differ by less than the inter-lab limits of agreement. That is the comparison that matters and the rounding does not change it.
AX-2026-043322
The certificate for lot CPC-2508-Y1913 states purity as a round figure. Integrated areas do not land on halves, so this is either a rounded presentation of a real integration or a release specification carried into the result field. Independent measurement here is 98.00 %, which is consistent with either.
AX-2026-042457
The declared figure for HOMO-2509-K4706 and the independent median differ by less than the inter-lab limits of agreement. That is the comparison that matters and the rounding does not change it.
AX-2026-042298
The certificate for lot TFC-2508-W1380 states purity as a round figure. Integrated areas do not land on halves, so this is either a rounded presentation of a real integration or a release specification carried into the result field. Independent measurement here is 99.01 %, which is consistent with either.
AX-2026-042093
The certificate for lot HYB-2512-P8025 states purity as a round figure. Integrated areas do not land on halves, so this is either a rounded presentation of a real integration or a release specification carried into the result field. Independent measurement here is 99.51 %, which is consistent with either.
AX-2026-042299

AX-2025-021102
The certificate for lot BCH-2505-Y5388 states purity as a round figure. Integrated areas do not land on halves, so this is either a rounded presentation of a real integration or a release specification carried into the result field. Independent measurement here is 97.97 %, which is consistent with either.
