VUV Hydrocarbons Analysis (PIONA, DHA etc.)
VUV system is compliant with ASTM D8071/D8267/D8368/D8369/D8519. Vacuum ultraviolet (VUV) spectroscopic detectors can provide a new dimension of chemical analysis accuracy for hydrocarbon analysis. VUV light creates unique spectral signatures in the gas phase that result in unambiguous compound identification and quantitative analysis across a wide spectrum of complex applications.
- Provides a lot of information in a fast, robust measurement.
- Relatively simple instrumentation, setup, and analysis procedures.
- Complies to method ASTM D8071
* The VUV detector VGA-100 is a product of VUV ANALYTICS, INC.

The VUV detector simplifies PIONA compound analysis in finished gasoline. The VUV absorption spectra demonstrate obvious class similarities, allowing for simplified compound class separation.
ASTM Method D8071
This is 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).
ASTM D8071 provides equivalent PIONA compound information that would otherwise require the use of multiple ASTM methods with complex setups and instrumentation. ASTM D8071 can be substituted for these methods.
ASTM Method D8267
This is standard test method for determination of total aromatic, monoaromatic and diaromatic content of aviation turbine fuels using gas chromatography with vacuum ultraviolet absorption spectroscopy detection (GC-VUV).
1. Results are easy to interpret results with no room for ambiguity.
2. Chromatogram overlays are provided for visual distinction of saturate, monoaromatic, and diaromatic content.
3. Detailed acquisition information is provided for analysis traceability.
ASTM Method D8368
This is standard test method for determination of totals of aromatic, polyaromatic and fatty acid methyl esters (FAME) content of diesel fuel using gas chromatography with vacuum ultraviolet absorption spectroscopy detection (GC-VUV).
Several methods have been developed to measure either the aromatic content or FAME content of diesel fuel. These methods are summarized in the below table. Analyzing both parameters has traditionally required the use of multiple analytical techniques and methods which adds complexity and cost to this type of analysis.

ASTM Method D8369
This is standard test method for detailed hydrocarbon analysis (DHA) by high resolution gas chromatography with vacuum ultraviolet absorption spectroscopy (GC-VUV)
Characterization of hydrocarbon streams, including speciation and quantitation, has traditionally been accomplished using DHA by GC-FID. Requiring long run times, very good chromatographic separation and significant human review from your most experienced user, traditional DHA has changed little since it was first introduced over 40 years ago.
The verified hydrocarbon analyzer (VHA)™ is a new approach to characterizing hydrocarbon streams at the component level that replaces traditional DHA. VHA™ is a modern approach to detailed hydrocarbon analysis that uses vacuum ultraviolet spectroscopy and spectral validation to deconvolve and identify critical components – accurately, without the need for human intervention, and in a fraction of the time of traditional DHA.
ASTM Method D8519
This is standard test method for determination of hydrocarbon types (saturates, olefins, styrenes, aromatics and polyaromatics) of Waste Plastic Process Oil (WPPO) from chemical or thermal processes using gas chromatography and vacuum ultraviolet absorption spectroscopy detection (GC-VUV).
This method is designed to accurately characterize WPPO produced from chemical or thermal recycling of waste plastics. With this technique, operators can identify and quantify hydrocarbons in WPPO more efficiently than ever before.
