[Advances of solid-phase microextraction and current status of application in food analysis].

Solid-phase microextraction (SPME) has been widely used as a sample preparation technique in current chromatography. SPME integrates extraction, concentration, desorption and injection in one step, which is highly sensitive and easy to operate. This review briefly introduces the evolution of the coating, equipment and corresponding techniques of SPME in recent years. It also summarizes SPME applications in food analysis and discusses some of the common issues found in quantitative analysis.
