What is group-type analysis in fuel testing?

Group-type analysis is a streamlined approach for characterising finished fuels like aviation turbine fuel (AVTUR). Rather than analysing individual chemical components, which can be complex and time-consuming, group-type analysis focuses on entire classes of hydrocarbons. This method provides a comprehensive overview of the fuel’s chemical composition by summing peak areas for different hydrocarbon groups. ASTM Method D8396 is a key standard used in this analysis, offering a simplified and effective way to assess fuel quality.

How does ASTM Method D8396 work?

ASTM Method D8396 specifies comprehensive two-dimensional gas chromatography (GCxGC) for detailed hydrocarbon analysis in fuels. This method is particularly beneficial for middle distillates such as aviation fuel and diesel. By separating hydrocarbons into well-defined classes, GCxGC enables precise quality control and insight into the production processes. With the growing importance of sustainable aviation fuels (SAFs), GCxGC’s ability to provide clear and actionable data is increasingly valuable. The method’s structured ordering allows for the straightforward reporting of chemical classes, reducing the need for complex mass spectrometers or sample fractionation.

Benefits of routine group-type analysis with GCxGC-FID

SepSolve’s GCxGC-FID offers enhanced capabilities for routine group-type analysis of middle distillates, including aviation fuel:

• Enhanced GCxGC performance: The proven reverse fill/flush design of the INSIGHT-Flow modulator is highly regarded in both research and routine analytical laboratories worldwide.
  
  

• Efficient reporting: ChromSpace software facilitates rapid data analysis and reporting, ensuring efficient management of group-type analysis results.
  
  

• Increased productivity: The dual-channel GCxGC setup enables simultaneous analysis of two samples, effectively doubling throughput.
  
  

• Flexible Integration: The INSIGHT-Flow system can be retrofitted to popular gas chromatographs, allowing existing GC-FID systems to upgrade with GC×GC capabilities.
