摘要
采用填充毛细管液相色谱 (PC -HPLC)与高温毛细管气相色谱 (CGC)在线联用技术分析润滑油全组分。PC -HPLC柱 ( 0 .32mmi.d .)用于样品族分离 (烷烃、单环芳烃、双环芳烃、三环芳烃和胶质 )。经PC -HPLC分离后的各族组分被依次存放在多位储存接口内 ,然后分别转入GC作单个族组分的定量分析。该方法是解剖进口润滑油基础油及新产品开发中强有力的分析手段。
By using the online technique of the packed capillary high performance liquid chromatography (PC-HPLC) and high temperature capillary gas chromatography (HTCGC), the lubricating oil components was analysd. The sample is separated into aliphatics, mononuclear aromatic hydrocarbon, dinuclear aromatic hydrocarbon, trinuclear aromatic hydrocarbon and resin by a PC-HPLC column (0.32mmi.d.). Each group separated by PC-HPLC column is cut down and stored in a multiplace interface, then is transfered into the HTCGC to be analysed. The method is the powerful analytical way to dissect the imported lubricating basic oil and develope new productions.
