Highlights from this day
  • mg_per_ml — tfa counterion runs higher by mass than acetate. if the certificate does not say, you cannot do the mass balance 22:38
  • mg_per_ml — water content is why an honest 10mg vial assays at 9.1. karl fischer titration, and most certificates omit it 22:49
  • void_volume — the font on this one changes halfway down, am i being paranoid 22:59
  • void_volume — coming back after 1 months, has the pinned reading guide changed 23:01
