Abstract Information :

Detailed Hydrocarbon Analysis (DHA) by ASTM Method D6730 uses high-resolution GC-FID to separate and quantify individual spark-engine fuel compounds, which can then be reported as paraffins, isoparaffins, olefins, naphthenes, and aromatics (PIONA). GC run time is long and post-processing data review is necessary to ensure accurate peak integration for closely eluting compounds.

GC with vacuum ultraviolet (VUV) absorption spectroscopy offers a new DHA approach. VUV spectra uniqueness enables deconvolution while class similarity of spectra permits PIONA reporting. DHA GC run time can be shortened to 50 min. Fully automated data processing produces a compound and class report in 90 sec.
