摘要: Very volatile organic compounds (VVOCs), such as methanol, acetaldehyde, ethanol, acetone, acetonitrile, and dichloromethane, were extracted from water samples using a needle-type extraction device based on purge trap analysis. The analytes could then be determined by gas chromatography-mass spectrometry. By introducing carbon molecular sieves the medium, aqueous VVOCs successfully needle. limit of quantification for dichloromethane 75, 7.5, 0.5, 10 0.5 μg/L, respectively. This newly developed method was also applied to determination in commercial samples, fruit juice.
