Loss on ignition (LOI) — botanicals & minerals
TL;DR
Loss on Ignition (LOI), per USP <281> total ash and AOAC equivalents, is the gravimetric ash test that confirms mineral purity (calcium carbonate, magnesium oxide, dicalcium phosphate) and botanical filth limits (total ash, acid-insoluble ash). A botanical with acid-insoluble ...
Loss on Ignition (LOI), per USP <281> total ash and AOAC equivalents, is the gravimetric ash test that confirms mineral purity (calcium carbonate, magnesium oxide, dicalcium phosphate) and botanical filth limits (total ash, acid-insoluble ash). A botanical with acid-insoluble ash above the USP/EP monograph limit indicates soil/sand contamination and fails identity-plus-purity even if HPTLC confirms species.

How V5 handles it
QMS — quality engineered into every action, not bolted on.
Because V5 owns the operator action, the QMS sees the data the second it’s captured — not at the end of the shift.
Document control with hard kiosk-level training enforcement.
Versioned SOPs are only useful if operators are actually trained on the current version. V5 enforces it at the kiosk.
