Analysis of Diesel Fuel Using GC×GC-MS
GC×GC is state-of-the-art chromatography technology that involves directly connecting two different columns together to achieve
high separation levels. GC Image was used to create two-dimensional results from analyzing diesel fuel using a GC×GC-MS system,
as shown to the left. A column with high polarity was used for the second column, which enabled separating aromatic hydrocar-
bons, which tend to overlap with paraffins. These can be detected as a blob distribution pattern that reflects the compound struc-
ture. System
