| 英文摘要 | the octadecylamine-capped gold nanoparticles (oda-au-nps) were prepared and directly used to coat the capillary wall. the hydrophobic coating acted as the stationary phase for open-tubular gas chromatography (otgc). the oda-au-nps can be adsorbed tightly onto the inner surface of fused silica capillary column via electrostatic interaction and enhanced interaction of van der waals between gold nanoparticles and the capillary wall. thus, the modification of the inner surface of capillary column by oda-au-nps can be achieved simply by flushing the capillary with a solution of oda-au-nps and the resulted oda-au-nps coating is very stable. no perceptible degradation in the oda-au-nps-based separation was observed after similar to 1900 sample runs. this type of columns also provided excellent chromatographic performances: high number of theoretical plates, outstanding run-to-run and column-to-column reproducibility and high selectivity for a wide range of test mixtures. an efficiency of 2474 theoretical plates per meter for chlorobenzene was obtained on an oda-au-nps-modified 1.6 m x 100 mu m i.d. fused silica capillary column.
