Highlights from this day
  • ema_vs_national — posting my Medutest result on lot A-2601, what do people make of it 15:24
  • ema_vs_national — is a purity-only test worth the money if underfill is the common failure 16:06
  • dana_titrates — log the boring results too. a channel that only records failures produces a false picture 17:23
  • split_shipment — follow up the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 17:32

quantity testing is usually a separate line item and it is the one worth paying for

EV

weigh the vial before you reconstitute. it costs nothing and catches the common failure, anyway

EM

99.4 against a certificate of 96.8 is fine. the same supplier landing low four times in a row is a question

SS

a supplier disputing a result is rare here and it has never gone well for the supplier

*Janoshik not the other one

the results in this channel skew because people test when they are suspicious. that is selection bias and it is real, for what its worth

slightly off topic but how do you post a result so it is actually useful to somebody in a year

EV

sorry to jump in i had a result i am fairly sure was a handling error on my side and i logged it as such

EV

while im here do the results in this channel skew because people test when suspicious
a result without a lot number and a purchase date is an anecdote with a pdf attached

SS

a point or two between the certificate and an independent result is inside what two labs disagree by

how do you separate batch variance from supplier variance

update from 24 months ago: retested the same supplier, result came back better, logged both

a single sample tells you about a single vial. that is genuinely all it tells you

DT

my vial assayed under label but the purity was fine, which matters more

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