GC methods for quantitative determination of benzene in gasoline

Pavlova A., Ivanova R.

Acta Chromatographica

2003

No. 13

215-225

GC-FID methods using two different capillary columns have been developed for the determination of benzene in gasoline samples and petroleum fractions. The methods were compared and evaluated. GC-FID with a PONA column is not appropriate for routine analysis. GC-FID with a TCEP column enables precise and accurate measurement of the benzene content of gasoline and petroleum fractions and can be widely used for analysis of petroleum products - there is no limitation of sample composition. Results obtained from analysis of commercial samples of gasoline and petroleum fractions agree with those obtained by use of the IR spectroscopy reference method.
