| Abstract: | Headspace solid-phase microextraction(HS-SPME) and gas chromatography coupled with mass spectrometry(GC-MS) were used for the qualitative determination of volatile compounds in white liquor samples.HS-SPME experimental conditions,such as sample volume in headspace glass vial,ionic strength,equilibrium temperature and time,desorption time were optimized.The best extraction performance was achieved under the following conditions: 40% sample volume in headspace glass vial with addition of 0.2 g/mL NaCl,30 min ... |
