Abstract: Methods and systems for quantifying olefinic hydrocarbons in a hydrocarbon sample are provided. The methods can include separating olefinic hydrocarbons from the hydrocarbon sample by high pressure liquid chromatography. The methods can further include measuring the proton resonance signals of the separated olefinic hydrocarbons and quantifying the weight percentage of different subtypes of olefinic hydrocarbons and hence the weight percentage of total olefinic hydrocarbons in the hydrocarbon sample based at least in part on the proton resonance signals.
