quantity testing is usually a separate line item and it is the one worth paying for
log the boring ones
assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem
post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later
a supplier disputing a result is rare here and it has never gone well for the supplier
sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
if you are testing to settle an argument you will not settle it with n of 1
i test roughly every tenth vial. it is a sampling strategy, not paranoia
thats a fill problem
Purity check: no report on file for lot H-2814. Nothing logged either way.
has a supplier ever disputed a result posted here
update on the earlier thing weigh the vial before you reconstitute. it costs nothing and catches the common failure
