Baldrich Ferrer Ingeniería aromatic hydrocarbon characterization liquid chromatography This paper features the development of a new methodology for the quantification of aromatic speciesin light and medium fractions derived from petroleum by means of High Performance Liquid ChromatographyAssociated to a Diode Array Detector (HPLC-UV-DAD). The proposed method is basedon the selectivity that the chromatographic system presents when used to separate and detect the aromaticcompounds with different number of rings that allow the quantification of defined species such as mono, diand tri-aromatics respectively. A mathematical algorithm was generated to obtain from the ultraviolet spectraof each one of the identified hydrocarbons families the concentration for each specie equivalent to the onegenerated by high resolution mass spectrometry hydrocarbon type analysis. The method applicability wasverified in light samples (diesel) with average relative errors of 1,18%, 3,30% and 15,21% in hydrocarbondetermination of mono, di and tri-aromatics respectively. The methodology was preliminary evaluated withlight and medium gas oils but unavailability of mass spectrometry data did not allow to test predictive accuracy.This instrumental technique is presented as an alternative for the characterization of light and mediumpetroleum fractions by HPLC-UV-DAD when traditional methods of analysis are not available 2006 artículo científico 0122-5383 https://www.redalyc.org/articulo.oa?id=46530211 en http://www.redalyc.org/revista.oa?id=465 CT&F Ciencia, Tecnología y Futuro application/pdf ECOPETROL S.A.
