Highlights from this day
- identity_shift — an identical chromatogram on two different lots is the single biggest tell there is, i think 16:26
- HPLC_Hank — two certificates from the same supplier have an identical chromatogram, is that normal 17:11
- VialBot — Testing queue: 7 submissions open, 52 awaiting dispatch. 17:22
- lot_number_lou — nobody can authenticate a certificate from a scan. you authenticate the material by testing it yourself 17:41

an identical chromatogram on two different lots is the single biggest tell there is, i think

sloppy not sinister
not evidence on its own
