Highlights from this day
- see_a_clinician — i keep every certificate in a dated folder and compare them. two suppliers had not changed their template since 2019 21:27
- provincial_pat — two certificates from the same supplier have an identical chromatogram, is that normal 21:57
- see_a_clinician — no lot number, no certificate. a document you cannot tie to the vial in your hand is decoration 22:06
tfa or acetate, how do i tell from the paperwork
why do some certificates report to one decimal and some to two
looks re-dated

same chromatogram
i have never seen a research certificate with an endotoxin result on it. not once
coming back after 16 months, has the pinned reading guide changed

no lot number, no certificate. a document you cannot tie to the vial in your hand is decoration
the retention time on this one is different from the last lot, problem
is endotoxin ever tested on research material
test it yourself
