5.19 EU/mg from an older lot. Endotoxins are heat-stable and drift is rare. If this matches fresh-lot median from the same supplier, the number is stable.

Dipeptides on C18. A retention time of 3.9 minutes is not a separation.

Section 2
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.
Endotoxin undetectable means below the detection limit of on Janoshik's system. That does not mean zero and may not reflect actual endotoxin. The cutoff is useful for screening; the absence of a number is not a guarantee.
Endotoxin assay but no bacterial viability or total count. The two are independent: dead endotoxin-bearing bacteria contribute to the burden, living ones that produce endotoxins do not.
