solid-phase micro-extraction (SPME)
SPME is a solvent-free solid-phase preconcentration technique based on the sorption of analyte species present in a liquid phase or, more often in a headspace gaseous phase, on a microfiber coated with a chromatographic sorbent. When the equilibrium is reached, the fiber is transferred to a GC injector by means of a microsyringe, and the analytes are thermally desorbed inside the heated injector.
