Cannabis Lab 101: Residual Solvents Testing, Headspace GC, and the Class 1/2/3 Limits
I walk through every step of cannabis residual-solvent testing: how USP <467> Class 1, 2, and 3 limits apply to extracts, why headspace GC is the right tool, how to set up calibration, and why an ethanol extract can still fail. Sourced to primary USP documents throughout.
