Automated Characterization of Fuel Stream Hydrocarbons

Complete characterization of spark engine components in fuel streams requires the use of complex instrumental setups, long GC method runs, and careful data analysis with a high degree of oversight. Individual gasoline analyte identification is often accomplished using detailed hydrocarbon analysis (DHA) using methods like ASTM D6730, which is highly dependent on chromatographic resolution and peak identification based on relative retention times. A gas chromatography – vacuum ultraviolet (GC-VUV) method was recently developed that follows ASTM D6730 conditions while eliminating the requirement for pre-column tuning. This method, VUV Verified Hydrocarbon Analysis (VUV-VHA), utilizes spectral and retention index information to confirm the identity of over 140 key gasoline analytes through an automated data analysis routine performed by VUV Analyze software.

In addition, the bulk analysis of paraffin, iso-paraffin, olefin, naphthene, and aromatic (PIONA) compounds is reported along with the speciated analytes in mass % or volume %. VHA data processing and review time averages 2–3 minutes per sample, in contrast to peak assignment procedures that can take 30 minutes or more. The webcast concludes with a discussion of opportunities to shorten GC run times of gasoline analysis methods while utilizing the capabilities of the VUV PIONA+ method to spectrally identify hydrocarbon compounds.
