These higher boiling components will be removed by vacuum distillation of the provided sample to permit facile gas chromatographic separation. 为了能顺利地进行气相色层分离,可以对所提供的样品进行真空蒸馏,把较高沸点的混合物除去。
Isobutane is typically used as a co-blowing agent with other hydrocarbons, so the effect of its low boiling point is somewhat diluted. 异丁烷一般是用于与其它碳氢化合物共混发泡,因此,其低沸点的特性对发泡的负面影响并不大。
