Abstract
The present disclosure provides a hybrid micro-gas chromatography column including a metal-organic framework (MOF) coating the inner wall of a channel, wherein the MOF is used as an adsorbent and a stationary phase for volatile organic compounds (VOCs) so that preconcentration and separation of VOCs are performed simultaneously. According to the present disclosure, it is possible to effectively achieve miniaturization of a portable gas chromatography (GC) system by providing a hybrid micro-gas chromatography column capable of simultaneously performing preconcentration and separation of low-concentration volatile organic compounds (VOCs).
