Highlights from this day

bench_notes — assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem 21:27
bench_notes — sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm 21:37
bench_notes — the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 21:39
LC_MS_Lena — do you test every order or sample it 21:42
LC_MS_Lena — the results in this channel skew because people test when they are suspicious. that is selection bias and it is real 22:13

has a supplier ever disputed a result posted here

is a purity-only test worth the money if underfill is the common failure

whats the underfill rate people are actually seeing

log the boring results too. a channel that only records failures produces a false picture

selection bias

test it again
