Agilent Technologies has released a two-dimensional gas chromatographic (2-D GC) method that can determine the purity of denatured fuel-grade ethanol when used as a gasoline additive. This analyzer can also measure thiophene concentration of benzene. The new chromatographical system is estimated to be nearly 10 times faster than the traditioal ASTM D5501 method. The 2-D GC system provides both precise qualitative and quantitative results.
