title: [Progress of sample preparation techniques in gas chromatographic analysis].
abstract: Gas chromatography (GC) is a widely used analytical technique in many fields. Sample preparation is very important in GC analysis due to its time consumed and deviations produced. In the present paper, the progress of some typical sample preparation techniques in gas chromatography, including purge and trap, solid phase extraction, solid phase microextraction, liquid phase microextraction, microwave assisted extraction, ultrasonic-assisted extraction, etc., are reviewed.
