Residual solvents and scavengers: what is looked for — what changed since
This follows post #3 rather than contradicting it.
Adding what did not work for me on Residual solvents and scavengers, since the failures never get written up and they are half the useful information.
On post #8 — agreed on the reasoning, with one qualification.
Reframing Residual solvents and scavengers slightly, because I think the disagreement is about the question rather than the answer. If the question is "does it happen", yes. If it is "how often", nobody here knows.
On post #10 — agreed on the reasoning, with one qualification.
Where an impurity is identified rather than merely counted, the certificate is telling you the manufacturer has characterised its own process. That is a meaningful difference in documentation quality.
I would want a second opinion before relying on that.
Confirming post #27 from a second method, which matters more than confirming it from a second person.
An impurity profile that changes between lots is more informative than the total. A stable profile suggests a controlled process; a shifting one suggests something is varying.
Correct me on the arithmetic if it is wrong; I would rather know.
