| Tartalmi kivonat: | The analysis and the comparative examination of hydrocarbon samples are very important from gcochemical aspects. To determine correlations for rock to rock, rock to disperse organic matter, oil to oil is one of the task of geochemistry. On the basis of the below introduced and presented method it is possible to analyse quikly significant number of oil samples of relatively small quantities. By so doing comparison and classification of a kind of crudes from different locations and depths can be made. From the experimental results the identity of production site or a migration route may be concluded. • The analysis comprises (i) the samples preparation to HPLC, (ii) the HPLC analysis (iii) the computer processing. During the analytical process of sample preparation for HPLC the crude oil or the chloroform soluble disperse organic matter were separated on a pre-column packed with silica gel for fractions eluated or non-eluated by «-hexane. The fraction eluated by «-hexane containing the n-hexane-eluated aromatic components was used for HPLC which are specials and characteristics of different oils so the chromatograms of the crudes and the disperse organic matters are suitable for comparative analysis (finger print). The computerized comparative analysis involves the determination of the location and heigth of peaks and the cluster analysis. The computer gives a plot of "dendrogram" showing the correlation of different types of crude oils and organic matters. |
