genuine question about VendorInvestigate that I am slightly embarrassed to ask
genuine question about VendorInvestigate that I am slightly embarrassed to ask — that is what I am asking, and I have already read the wiki twice. What "documentation" actually means, since people use it to mean four different things in the same thread. A certificate of analysis is one document about one lot. A batch…
This. Ask for the batch record. The ones who send it inside a day have told you more than any review could.
Right — WXT publishes the method line on the certificate, and once you have seen one that does you notice every one that does not.

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
Did the lot code on the vial match the paperwork?
That is a report count, not a test count. The table lists both and they are very different numbers.
