BTEX Determination in Gasoline Containing Ethanol by Single Oven MDGC

The determination of BTEX in gasoline is usually performed in accordance with the standard test method ASTM D3606 using gas chromatography. However, particularly in the presence of ethanol, co-elutions are observed in one-dimensional chromatography. In this application note a method is described applying multidimensional GC to overcome the separation problem.
