assay under label with good purity means you got less of the right thing. that is a fill problem, not a synthesis problem

Highlights from this day
- HPLC_Hank — the results in this channel skew because people test when they are suspicious. that is selection bias and it is real, ill dig out the number 12:52
- HPLC_Hank — how much does sample handling on my end affect the number 12:53
- two_three_lifts — what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern, ymmv 14:24
- ms_ms_mira — do you test every order or sample it 14:25
- two_three_lifts — i had a result i am fairly sure was a handling error on my side and i logged it as such quantity testing is usually a separate line item and it is the one worth… 17:10
*PeptideMeter not the other one
which lab
how many lots do you need before you can say anything about a supplier

one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally
update on the earlier thing if you are testing to settle an argument you will not settle it with n of 1
[edited]how do you post a result so it is actually useful to somebody in a year
whats the lot
is a purity-only test worth the money if underfill is the common failure
what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern, ymmv

do you test every order or sample it

certificate said 96.8 and the independent came back 99.2, is that a problem
i have never regretted spending the money on a test. i have regretted not testing twice
thats a fill problem
posting my VendorInvestigate result on lot A-2418, what do people make of it
i had a result i am fairly sure was a handling error on my side and i logged it as such
quantity testing is usually a separate line item and it is the one worth paying for
log the lot number
log the boring results too. a channel that only records failures produces a false picture
