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.
Purity and water are independent properties. An excellent chromatogram on a wet cake is entirely coherent and it is what this record shows.
Nothing about this record implicates the synthesis. Oxidation products form after cleavage and after purification, in the vial, and the timeline is in the custody block.
Silica in the secondary container extends the window in which a cake stays where the cycle left it. It is a few pence per shipment and it shows up in the numbers.
