本文提出了用高效凝胶色谱法(HPGPC)快速定量测定聚ω-烯烃合成润滑油中芳烃含量的方法。以μ-styragel(500-100-100,=10~(-4)微米)为固定相,以四氢呋喃作流动相。示差折光检测器检测。并从经典柱色谱法分离的芳烃作为标样进行了校正,对色谱条件、方法的准确度及精密度也进行了讨论。
This paper presents a rapid and quantitative method for the determination of aromatics content in poly-ω-olefin synthetic lubricating oils by high performance gel permeation chromatography (HPGPC). Using μ-styragel (500-100-100, = 10 ~ (-4) μm) as stationary phase and tetrahydrofuran as mobile phase. Refractive index detector detection. Aromatic hydrocarbons separated from classical column chromatography were calibrated as standard samples. The chromatographic conditions, the accuracy and precision of the methods were also discussed.
