[Question] reship — what am I missing here
reship — what am I missing here. Searched first, found three threads that contradict each other, hence the post. A certificate with a purity figure and no method line is not falsifiable. You cannot reproduce it, you cannot check it, and it tells you nothing about how the number was produced. Why the directory has two…
Where a supplier holds regional stock, ask which lines are actually held there rather than drop-shipped. It changes the lead time and it changes the customs question.
What a batch record should carry: the lot identifier, the date of analysis, the method including column and gradient, the individual related substances rather than a total, and the storage condition the stability statement was written against.
consistency across lots beats one spectacular result
the lot on the vial has to match the lot on the certificate, every time
Yes. Spread across lots is the number that tells you about the process. A single high result tells you about a vial.
What did they say when you asked for the method line?
