[Analyses of gasoline range hydrocarbons by gas chromatography].

Analyses of gasoline range hydrocarbons by gas chromatography are reviewed with 66 references. Methods of high resolution capillary gas chromatography, multidimensional gas chromatography, and gas chromatography with atomic emission detection after bromination are summarized respectively. The advantages and limitations of each method are discussed and solutions for some existing problems are proposed.
