Highlights from this day
- luerlok — my sheet has 4 lots from BCH with a spread under a point, which is tight, your mileage will differ 23:16
- HPLC_Hank — update from 20 months ago: retested the same supplier, result came back better, logged both, ask me again in a month 23:17
- HPLC_Hank — i had a result i am fairly sure was a handling error on my side and i logged it as such 23:21
- area_percent — how do you separate batch variance from supplier variance 23:35

is quantity testing available as a separate thing or bundled
thats a fill problem
attach the pdf
weigh it first
for the archive how many lots do you need before you can say anything about a supplier
99.4 against a certificate of 96.8 is fine. the same supplier landing low four times in a row is a question
how do you separate batch variance from supplier variance

genuine question how much does sample handling on my end affect the number
for the archive i have never regretted spending the money on a test. i have regretted not testing twice, i have it written down somewhere
weigh the vial before you reconstitute. it costs nothing and catches the common failure
