在理论推导和实验验证的基础上提出了文题的分析方法。采用两种折光率不同而分离特性相似的流动相,根据样品在两个流动相中两个谱图联立求解各组分浓度和折光率。对渣油芳香馏分环分布和渣油分子量分布进行了测定。环分布采用苯、萘、蒽、窟苯并芘等标记物质的洗提时间的两两平均值作为分割限。分子量分布采用聚苯乙烯和正构烷烃标样,分子量和淋洗体积在两种流动相中总线性相关系数为0.99。
On the basis of theoretical derivation and experimental verification, this paper proposes a method of analyzing the essay. Using two different refractive index and separation of similar characteristics of the mobile phase, according to the sample in both mobile phase two simultaneous determination of each component concentration and refractive index. The residue distribution of aromatic fractions and residue molecular weight distribution were measured. Ring distribution using benzene, naphthalene, anthracene, cave benzo [a] pyrene and other marking substances elution time average of two or two as a partition limit. The molecular weight distribution of polystyrene and n-alkanes standards, molecular weight and leaching volume in the two mobile phase total linear correlation coefficient of 0.99.
