- ... A method based on headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) was used for the analysis of volatile compounds in “Hengshui Laobaigan” liquor. Five different fibers were evaluated in terms of the number of volatile compounds, sensitivity and reproducibility. The results showed that 50/30 μm divinylbenzene/carboxen/polydimethylsiloxane (D ...
