This method is for determining individual components in C2 through C5 gaseous hydrocarbon mixtures. Most olefins including 1-butene and isobutylene are separated, although some are not sufficiently resolved for individual determination. The lower limit of detection for a single component is 0.05 mol-%. C6 and heavier components, if present, may not elute quantitatively from the system or may interfere with present or subsequent analyses.
