one data point
is it worth testing if the vial has already been through a warm transit
has a supplier ever disputed a result posted here
a point or two between the certificate and an independent result is inside what two labs disagree by
i test roughly every tenth vial. it is a sampling strategy, not paranoia

is quantity testing available as a separate thing or bundled

log the boring ones
i had a result i am fairly sure was a handling error on my side and i logged it as such
underfill is more common than impurity. if you only test purity you are testing the less likely failure
nice result
my sheet has 7 lots from KP with a spread under a point, which is tight
which lab
log the boring results too. a channel that only records failures produces a false picture
does a bad result on one lot condemn the whole supplier
