Decontamination Wash
Definition
A multi-solvent surface wash (typically dichloromethane, methanol and aqueous buffer) applied before digestion to strip externally deposited drug from the cuticle. The wash itself is retained and analysed separately so the analyst can compare internal versus external loading and rebut a passive-exposure defence.
