Abstract
Abstract A gas chromatographic method has been developed for the determination of the synthetic fragrance musk, 7-acetyl-6-ethyl-1,1,4,4-tetramethyltetralin (AETT). The fragrance is first added to water and extracted with ether to separate the fragrance oil from the water-alcohol mixture. The AETT, present in the ether-soluble fraction, is purified further by preparative high pressure liquid chromatography (HPLC). The AETT in the collected HPLC fraction is then determined by gas chromatography using external standardization. Recoveries from samples spiked with AETT at levels ranging from 100 to 1000 μg/mL varied from 80 to 96% with an average of 90%. AETT was verified in each sample by gas chromatography/mass spectrometry.
