An Aijiren Guide to SPME Analysis

Solid Phase Microextraction (SPME) is a fast, solvent-less sample extraction technique. It is used for extracting organics from a matrix (solid, liquid, or gaseous) into or onto a stationary phase immobilized on a fiber. In SPME, analytes establish equilibria among the sample matrix, the headspace above the sample, and a polymer-coated fused fiber.
