| titleOfInvention | Solid phase micro-extraction method for unsaturated compound |
| abstract | The invention discloses a solid-phase micro-extraction method of an unsaturated compound. The invention relates to a novel solid-phase microextraction method of unsaturated compounds, which is established by taking a silver nanoparticle functionalized monolithic column prepared by an In-situ reduction method as a solid-phase microextraction monolithic column and combining an In-tube solid-phase microextraction-high performance liquid chromatography-diode array online combined detection system (In-tube SPME-HPLC-DAD). According to the invention, the enrichment of unsaturated compounds on the silver nanoparticle functionalized monolithic column is realized by utilizing the special acting force between the silver nanoparticles loaded in the monolithic column material and unsaturated carbon-carbon double bonds carried by the unsaturated compounds; and because the strength of the action force between the silver nanoparticles and cis-trans isomers of the unsaturated compound is different, the sequential elution of the cis-trans isomers of the unsaturated compound is further realized, and the requirements of efficient detection of trans-fatty acid and separation and analysis of cis-trans-stilbene are met. |
