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

Determination of polynuclear aromatic hydrocarbons in human blood serum by proteolytic digestion — direct immersion SPME
TL;DR: In this paper, a proteolytic digestion method for the determination of polynuclear aromatic hydrocarbons (PAHs) in human blood serum has been developed, where non-specific serine protease, Proteinase K, was employed to remove the fouling of the SPME stationary phase by the lipoprotein in blood serum during extraction.

Calibration procedure for solid phase microextraction-gas chromatographic analysis of organic vapours in air.
TL;DR: A calibration procedure for solid phase microextraction-gas chromatographic analysis of organic vapours in air was described in which GC detector (MS in this case) signal is directly related to concentration of analytes of interest sampled by SPME.
