Summary:The paper is focused on the identification of laboratory quantities of n-butanol and isobutanol by gas chromatography GC-FID. Gas chromatography (GC) is a type of separation method. It is based on separation of components contained in the test sample that can be converted into the gas phase without decomposition. The process of separation of substances takes place in the gas chromatograph column. The mobile phase is always a gas which is in contact with the stationary phase. This assessment is also based on the application of n-butanol and isobutanol as high-percentage blends for possible future use. For laboratory analysis various combinations of fuels were collected containing gasoline with always one of the alcohols or with both together. The result is a chromatographic record, which is characteristic for each petroleum fraction. Using the chromatogram can clearly identify the presence of alcohol, which is necessary to ensure and check the prescribed amount of alcohol in the fuel. Gas chromatography can thus supplement the results of the evaluation of standard fuel or narrow selection of test parameters. The proposed method is an alternative to commonly used multidimensional chromatography.
