HPLC ANALYSIS OF PERYLENE IN AROMATIC HYDROCARBON FRACTION

Central Laboratory of Petroleum Geology, Ministry of Geology and Mineral Resources

摘要: 应用有机地球化学的方法,进行陆相油源及含油气盆地有机质沉积环境等研究中,岩石芳烃组份中(艹北)的地球化学特征,引起了一些研究者的重视,国内已见有这方面的报导。有关(艹北)的分离和测定,曾有人使用薄层法,先从芳烃组份中制备出"(艹北)"馏份,然后再用紫外或荧光光谱法测定(艹北)的含量。但是,由于薄层板效所限,使得"(艹北)"馏份中尚存其他化合物,直接影响了定量分析。为此,我们在芳烃组份分离试验的基础上,开展了对岩石芳烃中(艹北)的高效液相色谱测定方法的研究。

Abstract: HPLC with two cells of UV-visible spectrophotometric detector is used in this measuring method.While the aromatic hydrocarbon fraction is being eluted from column,qualitative and quantitative analyses of perylene are accomplished.The result shows that it is a rapid and reliable method.The limit of detection of perylene is 0.02 ng (0.005 AUFS).
