  • METHOD TO MEASURE OLEFINS IN A COMPLEX HYDROCARBON MIXTURE
    Publication number: 20070137481
    Abstract: A method to measure the quantity of olefin species in a complex hydrocarbon mixture by means of comprehensive multi-dimensional gas chromatography, involves passing a sample of a hydrocarbon mixture through a first capillary column comprising a dimethyl-polysiloxane stationary phase, subjecting the sample to a thermal modulation before entering a second column comprising a 50% phenyl, equivalent, polysilphenylene-siloxane stationary phase, wherein the introduction bandwidth into the second column is smaller than 20 milliseconds.
