whats the lot
#test-results 2024-06-08
- week_three_wall — post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later 18:04
- pinch_not_stretch — genuine question a single sample tells you about a single vial. that is genuinely all it tells you, ill dig out the number 18:50
- retention_time — assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem, take that with a pinch of salt 19:07
- retention_time — the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 19:11
post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later

whats the worst result anyone has logged and what happened next
thats not great
anyone had a result they think was a lab error rather than a bad vial
the widest spread in my data is about 2.6 percentage points across five lots from one supplier
coming back after 10 months with a follow up result, where do i put it
weigh it first
quantity testing is usually a separate line item and it is the one worth paying for
genuine question a single sample tells you about a single vial. that is genuinely all it tells you, ill dig out the number
how many lots do you need before you can say anything about a supplier
a result without a lot number and a purchase date is an anecdote with a pdf attached
does a bad result on one lot condemn the whole supplier
selection bias
log the lot number
assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem, take that with a pinch of salt
is anyone tracking results over time in a way they would share
[edited]the honest limits: hobby chain of custody is weak and any result here should be read with that in mind
the results in this channel skew because people test when they are suspicious. that is selection bias and it is real
