摘要
直接用毛细管气相色谱法测定液体石蜡及原料中正构烷烃含量和碳数分布。应用毛细管柱上进样技术和长２５ｍ、内径０．３２ｍｍ、固定相液膜厚度０．１μｍ的高温镀铝石英毛细管柱，采用程序升温法对液体石蜡及其原料进行研究。方法快速、简便，定性、定量准确，精密度高，实用性强。
Determination of the
contents of normal paraffins and carbon number distribution in liquid paraffin wax and its
feedstock by means of capillary gas chromatography was reported in this paper. Liquid
paraffin wax and its feedstock were studied by using on-column injection, high temperature
quartz capillary column coated with aluminum and the method of programmed temperature.
This method has the advantage of simplicity, convenience, accuracy in quantitative analysis,
high precision.
