Abstract: The results from the quantification of hydrogen content in hydrocarbon mixtures and heavy petroleum fractions by integration of the signals in their high resolution 1H NMR spectra are presented and discussed. The results show the possibility of fast and precise quantification of hydrogen in 37 structural fragments, in addition to the total hydrogen in the sample by application of unified integration intervals. In contrast to the literature procedures, the hydrogen measurement is possible with less amount of sample in solution, with low pre-scan times, d1, with no strict temperature control, without the addition of any relaxation agent, and avoiding the need of an external reference.
