Highlights from this day
while im here is quantity testing available as a separate thing or bundled

whats the worst result anyone has logged and what happened next
log the boring results too. a channel that only records failures produces a false picture
how much does sample handling on my end affect the number
❤️3🎉6
quick one a supplier disputing a result is rare here and it has never gone well for the supplier
i test roughly every tenth vial. it is a sampling strategy, not paranoia

quantity testing is usually a separate line item and it is the one worth paying for, happy to be corrected
is a purity-only test worth the money if underfill is the common failure

underfill is more common than impurity. if you only test purity you are testing the less likely failure, your mileage will differ
log the boring ones
[edited]does a bad result on one lot condemn the whole supplier
[edited]genuine question is anyone tracking results over time in a way they would share
