GC-VUV PIONA+TM Method Characterizes the Bulk Composition of Hydrocarbon Groups and Select Individual Compounds in Gasoline
Austin, TX, March 3, 2017 (Newswire.com) – VUV Analytics VUV Analytics Inc. is pleased to announce the approval of its first ASTM International method, D8071 for the analysis of finished gasoline. The D02 committee meeting approved it as “Standard Test Method for the Determination of Hydrocarbon Group Types and Select Hydrocarbon and Oxygenate Compounds in Automotive Spark-Ignition Engine Fuel using Gas Chromatography with Vacuum Ultraviolet Absorption Spectroscopy Detection (GC-VUV).” The method provides complete PIONA compound class characterization in a single measurement, potentially replacing the use of multiple legacy methods for this analysis.
“The setup procedure is easy and requires no pre-column tuning or valve timing adjustments,” says ASTM member Dan Wispinski, laboratory manager at InnoTech Alberta. “The standard allows for faster run times because of the test method’s ability to handle co-elution among various species and hydrocarbon classes. It is a testament to the ASTM process that enables new technology to be quickly incorporated into mainstream use” says Wispinski.
Method D8071, available commercially as VUV PIONA+, uses straightforward instrumentation: a gas chromatograph, a standard 30m nonpolar column, and a VGA detector. Bulk concentrations of the hydrocarbon classes of paraffins, isoparaffins, olefins, naphthenes, and aromatics (PIONA) are determined. Specific analytes can also be singled out for further characterization.
” The rapid approval process by ASTM demonstrates the great support we’ve received from our lead customers and the D02 committee,” said Sean Jameson, Senior Vice President of Business Development at VUV Analytics. He added, “Our thanks to the many people who helped make it happen.”
