Parallel chemical absorbers combined with dual flame ionization detectors are used to determine the olefinic, paraffinic, and aromatic constituents in hydrocarbon gas mixtures.Design of the analyzer and a description of its various modes of operation are given. Applications illustrating its use include chromatographic analysis of gases in which the olefinic and paraffinic components are separately recorded, continuous analysis of auto exhaust for olefinic and paraffinic content during cyclic operation, studies of the effect of engine spark timing on the paraffinic and olefinic content of exhaust gases, and determination of olefinic, paraffinic, and aromatic content of gasolines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
