99.4 against a certificate of 97.4 is fine. the same supplier landing low four times in a row is a question

Highlights from this day
- LC_MS_Lena — i told WXT about a result they would not have liked and they did not argue. credit where it is due, thats just me 22:05
- VialBot — Reminder for LC_MS_Lena: dose day is today. Set 3 days ago. 22:08
- ferritin_fay — how do you post a result so it is actually useful to somebody in a year 22:14
- VialBot — Batch lookup B-0114: 7 independent reports on file, earliest 2025-07-07. 23:10
one bad test does not condemn a supplier. one good test does not clear one. both halves get ignored equally
a point or two between the certificate and an independent result is inside what two labs disagree by
log the boring ones

my result contradicts the supplier certificate, do i tell them
anyone tested the same lot twice at different labs
log the boring results too. a channel that only records failures produces a false picture
when did you buy it
lot bought purity assay/label

posting my Janoshik result on lot G-0641, what do people make of it
whats the underfill rate people are actually seeing
my read after three years of this: purity is mostly fine across the market and fill consistency is where suppliers differ
log the lot number
a supplier disputing a result is rare here and it has never gone well for the supplier, n of 1 obviously
*Medutest not the other one
do you test every order or sample it

right so is quantity testing available as a separate thing or bundled
test it again

slightly off topic but do the results in this channel skew because people test when suspicious
