通过固相微萃取 (SPME) 和搅拌棒吸附萃取 (SBSE) 分析混合苏格兰威士忌，以研究挥发物的组成。对于 SPME 分析，比较了三种不同的纤维：聚（二甲基硅氧烷）（PDMS）（100 μm）、聚（丙烯酸酯）（PA）（85 μm）和聚（二甲基硅氧烷）上的二乙烯基苯-Carboxen（DVB-CAR-PDMS）（50/30 μm）。结果发现，PDMS 和 DVB-CAR-PDMS 纤维表现出比 PA 更高的富集能力，以及更好的重现性。研究了采样时间、温度和加盐对挥发物富集的影响以及液体和顶空固相微萃取的差异。开发了最佳固相微萃取方法。最后，对一种更新的样品制备技术（即 SBSE）进行了评估，以提取威士忌挥发物。 （三）。 2002 Elsevier Science B.V. 保留所有权利。
Blended Scotch whisky was analysed by solid-phase microextraction (SPME) and stir bar sorptive extraction (SBSE) to study the composition of the volatiles. For SPME analysis, three different fibres were compared, poly(dimethylsiloxane) (PDMS) (100 mum), poly(acrylate) (PA) (85 mum) and divinylbenzene-Carboxen on poly(dimethylsiloxane) (DVB-CAR-PDMS) (50/30 mum). It was found that the PDMS and DVB-CAR-PDMS fibres showed a higher enrichment capacity than PA, as well as a better reproducibility. The influence of sampling time, temperature and salt addition on the enrichment of volatiles as well as the difference between liquid and headspace SPME were studied. An optimum SPME method was developed. Finally a more recent sample preparation technique, namely SBSE was evaluated to extract whisky volatiles. (C). 2002 Elsevier Science B.V. All rights reserved.
