GC-VUV

Analysis of Mono- and Di-aromatics in Jet Fuel (GC-VUV)

This technique combines classical gas chromatography with UV detection in the high-energy wavelength range of 125 – 240 nm or 125 – 430 nm. In this wavelength range, electron transitions to excited states are induced in almost all chemical bonds. The individual absorption of different bonding relationships leads to characteristic spectra, which can be used to assign individual compounds to different compound classes. In particular, this method enables effective differentiation between olefins and naphthenes.
We offer the following using this technique:
  • Quantification of aromatic compounds in jet fuel and SAF according to ASTM D8267
  • PIONA and oxygenate analysis of gasoline according to DIN EN 18015 or ASTM D8071
  • Detailed hydrocarbon analysis (VHA) of gasoline and naphtha according to ASTM D8369 (cf. DHA according to ASTM D6730)
  • Analysis of Waste Plastic Process Oil (WPPO) according to ASTM D8519 (expected from Spring 2025)

Schematic Layout of the VUV Detector

The VUV detector consists of a deuterium lamp, flow cell, and photo detector. Depending on the chemical bonding relationships, absorption occurs at different wavelengths, creating characteristic spectra that enable clear identification of chemical compound classes and can be used for quantification according to the Lambert-Beer law.

Chromatogram of a Conventional Jet Fuel

The absorption of saturated compounds from 125 – 160 nm is marked in red, while the absorption of aromatic compounds from 170 – 200 nm is marked in green. Based on the characteristic absorption ranges, mono- and di-aromatic compounds are identified.

Using specific response factors, the detected absorptions can be directly converted into mass or volume percentages.
