Highlights from this day
i have never regretted spending the money on a test. i have regretted not testing twice
attach the pdf
99 against a certificate of 98.1 is fine. the same supplier landing low four times in a row is a question
my sheet has 9 lots from ERP with a spread under a point, which is tight
posting my Janoshik result on lot D-0718, what do people make of it

thats within range
one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally, someone check my working
whats the lot
*PeptideMeter not the other one
a result without a lot number and a purchase date is an anecdote with a pdf attached
i had a result i am fairly sure was a handling error on my side and i logged it as such
coming back after 3 months with a follow up result, where do i put it
weigh the vial before you reconstitute. it costs nothing and catches the common failure
[edited]log the boring results too. a channel that only records failures produces a false picture
sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
a single sample tells you about a single vial. that is genuinely all it tells you
Reminder for power_through_no: dose day is today. Set 5 days ago.
when did you buy it

my vial assayed under label but the purity was fine, which matters more
the honest limits: hobby chain of custody is weak and any result here should be read with that in mind

assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem
does a bad result on one lot condemn the whole supplier
