TLDR
The solid phase microextraction (SPME) technique as mentioned in this paper involves exposing a fused silica fiber that has been coated with a stationary phase to and aqueous solution containing organic contaminants.Abstract:
The solid-phase microextraction (SPME) technique involves exposing a fused silica fiber that has been coated with a stationary phase to and aqueous solution containing organic contaminants. The analytes partition into the stationary phase until an equilibrium has been reached, after which the fiber is removed from the solution and the analytes are thermally desorbed in the injector of a gas chromatographread more
