Comprehensive two-dimensional gas chromatography (GC×GC) enables detailed separation of complex fuel samples and their classification into different substance classes and individual components.
ASG builds on years of expertise in this field and offers various established methods for analyzing middle distillates and higher-boiling samples.
Using GC×GC – FID, detailed quantification can be achieved for all fossil middle distillates (jet fuel, diesel, heating oil) and sustainable fuels (e.g., HVO, SAF). Our in-house method ASG 2502 follows ASTM D8396.
For higher-boiling samples, HT – GC×GC – FID is available with our in-house standard ASG 2501.
Even greater information content can be achieved using GC×GC – ToFMS. The coupling with time-of-flight mass spectrometry enables rapid detection of mass spectra across a wide mass range. Subsequent script-based data analysis allows automated assignment of detected mass spectra to corresponding substance classes. We offer a method for the boiling range of middle distillates (ASG 2253) and for higher-boiling samples (ASG 2221).
In the following figure, you can see a representative two-dimensional chromatogram of conventional diesel fuel according to EN 590, along with the results of data analysis and quantification. The separation was achieved using a “reverse phase column combination” consisting of a 50% phenyl-substituted column as the first dimension and a 100% polydimethylsiloxane column as the second dimension.
