Abstract

BALDRICHF, C.A. DIESEL CHARACTERIZATION BY HIGH RESOLUTION MASS SPECTROMETRY-GAS CHROMATOGRAPHY. C.T.F Cienc. Tecnol. Futuro [online]. 1998, vol.1, n.4, pp.65-73. ISSN 0122-5383.

High-resolution mass spectrometry-gas chromatography is combined with the HC22 method in order to obtain a detailed information about the chemical composition of diesel and the distribution of different compound types in terms of its final boiling temperature from a single analysis. The total time elapsed from sample injection and signal processing to obtain final results is 90 minutes. This fact makes this methodology a new and very important tool for the decision making process concerning the most suitable final boiling temperature and the type of treatment of the product in order to obtain diesel that fulfills the international standards. The consistency and repeatability of the experimental results are demonstrated.

Keywords : hydrocarbon group type analysis; high resolution mass spectrometry; diesel.
