This method is for determining the carbon structure of C7 and lower boiling compounds in debutanized olefinic samples. Complete hydrogenation is accomplished directly in the chromatograph injection system, enabling a carbon structure determination to be made. The limit of detection for any single carbon structure is 0.1 wt-%. Quantitative results are obtained through the use of an internal standard.
