Highlights from this day
- ring_size_down — anyone had a result they think was a lab error rather than a bad vial 17:29
- VialBot — New independent result logged — FGP, lot A-2601, purity 97.4% (Janoshik). 18:18
- HPLC_Hank — sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm, for what its worth 18:19
- VialBot — Purity check: no report on file for lot B-0329. Nothing logged either way. 19:08
- HPLC_Hank — i told SSA about a result they would not have liked and they did not argue. credit where it is due 20:32
i test roughly every tenth vial. it is a sampling strategy, not paranoia
thats within range

if you are testing to settle an argument you will not settle it with n of 1
a single sample tells you about a single vial. that is genuinely all it tells you
log the boring ones

how many lots do you need before you can say anything about a supplier
