ASTM D8071-17: Standard Test Method for 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) offers an excellent alternative to other techniques to determine Paraffins, Isoparaffins, Olefins, Naphthenes, and Aromatics in a quick and automated way. The unique- and class-indicating nature of absorbance spectra allow much faster analysis times and VUV Analyze software turns the data into actionable results with the push of a button. For those who require speciation of more than benzene, toluene, ethylbenzene, xylenes, naphthalene, methylnaphthalenes, iso-octane, methanol, and ethanol, which are quantified categories in D8071, VUV Analytics is developing a Detailed Hydrocarbon Analysis approach based on ASTM D6730. We term this VUV Verified Hydrocarbon Analysis, or VUV-VHA. I’ll be rolling this out in a webinar sponsored by LCGC on Tuesday, April 17, 10:00 CDT, so if you have interest, please register at the link below.
And if you’re wondering about the blog post title, “Turn Your DHA into VHA with DH, eh?”, that last bit is a nod to one of our favorite Canadians at VUV Analytics, Dale Harrison, our Chief Technical Officer, one of the inventors of the VUV detector. Dale is living proof that excellence from Canada is much more than hockey and curling!
