摘要

摘要: 应用一种新型高效的预处理装置——气流吹扫-注射器微萃取仪(GP-MSE),对原油样品进行预处理,并利用全二维气相色谱-飞行时间质谱对样品中金刚烷化合物进行了定性定量分析。结果表明,GP-MSE与传统柱层析法相比,具有快速、操作简便、回收率高、重现性好等优点。单金刚烷、双金刚烷的相对标准偏差分别为1.57%和2.63%,能有效对原油样品进行净化和富集;与直接进样相比,相对偏差均小于9%,相关系数均大于0.997。

Abstract: A novel device, termed as gas purge microsyringe extraction (GP-MSE), has been developed and applied to the preparation of different kinds of oil samples, including condensates, light and normal oils for the first time.Oils from the Pearl River Mouth Basin were firstly extracted by GP-MSE and then qualitatively and quantitatively analyzed by comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC-TOFMS).The proposed method has many advantages over traditional column chromatography, such as simple and fast steps, satisfactory recoveries, and lower consumption of solvents and samples.The relative standard deviations (RSD%) of adamantane and diamantane are 1.57% and 2.63%, respectively.Crude oil samples are purified and enriched effectively. The relative deviation is less than 9%, and the correlation coefficient is over 0.997.
