Abstract:
Laboratories facing the challenge of quantifying both benzene and toluene in finished motor and aviation fuel containing ethanol, must use the modified ASTM D-3606-17 method mandated by the US EPA. This column set prevents the co-elution of benzene with ethanol thus assuring accurate quantification of benzene. Toluene quantitation is straight forward in that there are no co-elution issues. The scope of the method for quantifying benzene is 0.1% to 5% by volume and the toluene range is 2% to 20% by volume. With the addition of butanol blended fuel slowly entering the market, this same packed column set with a slight modification of the GC oven parameters and also uses methyl ethyl ketone (MEK) as the internal standard can be used for the analysis of ethanol free gasoline containing butanol blend with no concerns of inconsistent retention times and/or co-elutions of critical components. This packed column set will satisfy both part A and Part B of the D 3606-17 method.
