| Abstract: | An accelerated solvent extraction(ASE) method has been developed to determine five polycyclic musk fragrances in fish samples by GC-MS.Fish samples were extracted by n-hexane,cleaned up by gel permeation chromatography(GPC) and activated neutral Al2O3 column.The final elute was concentrated with nitrogen before injection.Identification was carried out by GC-MS selective ion monitor(SIM) mode.The recovery of fluenthene-d10,surrogate standard,was from 92.7% to 112.9%.The limits of detection were from 0.20 to ... |
