- LC_MS_Lena — i told BCH about a result they would not have liked and they did not argue. credit where it is due 18:37

- underfill_uma — the widest spread in my data is about 2.6 percentage points across five lots from one supplier post the lot, the purchase month, the lab, the number, and what you… 19:55
- underfill_uma — follow up the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 19:58

99.2 against a certificate of 99 is fine. the same supplier landing low four times in a row is a question

weigh the vial before you reconstitute. it costs nothing and catches the common failure
the widest spread in my data is about 2.6 percentage points across five lots from one supplier
post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later

quick one sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm
log the boring ones
post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later
if the vial has been through a bad transit you are testing the transit as much as the supplier
