Abstract

 
 
 
 Monolithic solid phase microextraction silica sorbent coated with silver nanopar ticles (Ag NPs) was successfully synthesized in a small quartz capillary. The sorbent was tested in a headspace microextraction mode using various aromatic compounds followed by gas chromatography analysis. Due to the π-π electronic interaction between analytes aromatic systems and silver particles immobilized on the sorbent surface, the analytes were successfully extracted from a sample headspace and determined by gas chromatographic analysis.
