| 摘要 |
<p>The invention relates to a method for the quantitative analysis of hydrocarbon mixtures containing oxygenated compounds, in particular biofuels, using a flame-ionisation detector coupled to a gaseous-phase chromatography column, that comprises injecting a sample of a mixture to be analysed into the column and drawing at the detector output a chromatogram comprising a series of peaks each corresponding to one of the constituents of the mixture, characterised in that, for each of the constituents i of the mixture to be analysed, it comprises calculating a theoretical response factor RFi using the formula (I) in which ci is the number of carbon atoms in the constituent i, oi is the number of oxygen atoms in said constituent, Mc is the atomic mass of carbon, Mo is the atomic mass of oxygen, Mi is the molar mass of the constituent i, Cref is the number of carbon atoms in a reference compound, and Mref is the molar mass of said reference compound.</p> |
