用单一色谱柱不能一次测得煤油中正烷烃碳数分布与单体正烷烃绝对含量,往往先分离出正烷烃再上色谱。用5A分子筛柱测定煤油中正构烷的含量,外标法定量,由于液体进样量不易重复,分析结果的重复性受到影响。浩瀚色谱（山东）应用技术开发有限公司采用填充柱、5A分子筛柱串联分析,柱效高，分离好，结果满意。

The carbon number distribution of n-alkanes in kerosene and the absolute content of monomer n-alkanes in kerosene cannot be measured at one time with a single chromatographic column, and n-alkanes are often separated first and then chromatographed. The content of n-alkanes in kerosene was determined by 5A molecular sieve column, and the external standard method was used to quantify it. The repeatability of the analysis results was affected because the liquid injection volume was not easy to repeat. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts packed column and 5A molecular sieve column for series analysis, which has high column efficiency, good separation and satisfactory results.
