Abstract
A solid phase microextraction (SPME) fiber including a fiber and a deactivated surface-bonded sol-gel coating on a portion of the fiber to form a solid phase microextraction coating on the portion of the fiber, wherein the solid-phase microextraction coating is capable of preconcentrating trace organic compounds in various matrices. A sol-gel method of preparing SPME fibers with chemically bonded stationary phase coatings that serve as solvent-free extraction media including the step of chemically bonding the sol-gel stationary phase with the SPME fiber surface during its creation through sol-gel reactions.
