Re-injecting the same vial on a fresh column normally returns an asymmetry under 1.2 and a purity within repeatability of the original. That is the correct next step and it is cheap.
asymmetry_1p2
Peak asymmetry and tailing. Above 1.5 the integration is a guess.

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. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.
Agreed with the reading above.
