Vacuum Ultraviolet Spectroscopy
Universal and Unambiguous
Characterized by very short wavelengths of light, VUV spectroscopy is a universal, mass-sensitive detection technique that provides both quantitative and qualitative data. Because almost all gas phase molecules absorb strongly in the vacuum ultraviolet region, VUV spectroscopy is well-suited for analysis of fuels. It is possible to obtain a specific spectrum even for hydrocarbons which are subtly different such as structural isomers, and to easily and accurately identify them.
Easy to set up, easy to use

VUVision™ software simplifies GC analysis by providing an intuitive interface for analyte characterization by VUV spectroscopy. VUVision delivers straightforward workflows for acquiring and processing data, resulting in high automation confidence and low risk of analytical error.
VUVision is the base software for system control, data acquisition, library searching, qualitative analysis, calibration, and quantitative analysis by external or internal standard methods. It is intended for both manual post-processing and automated analysis driven by VUV Analyze which is the powerful post-acquisition software to support ASTM methods.
This robust software solution delivers standard chromatographic capabilities and data analysis while providing spectral information that is unique to VUV spectroscopy.

Maximize the Value of Your Investment by Running Numerous Methods on One Analyzer
The VUV Analyzer for Fuels is a platform developed with value, ease-of-use, and flexibility in mind. Running multiple methods on one VUV Analyzer for Fuels allows you to rapidly switch between different analyses using the same GC, detector, and software. This simplifies operation for the analyst and accelerates analysis time across methods, including: ASTM D8071/ASTM D8369 (gasoline), ASTM D8267 (jet fuel), ASTM D8368 (diesel) and ASTM D8519 (pyrolysis oil). 
Application-Specific Spectral Libraries
Unique and Comprehensive Spectral Libraries for Unambiguous Identification
Each application developed to run on the VUV Analyzer for Fuels includes a comprehensive spectral library specific to the method being run. The high-resolution spectra contained in these libraries provide unambiguous identification and reduce the need for baseline-resolved chromatography, ensuring accurate results every time. For added flexibility, the VUV Analyzer for Fuels makes it easy to extend these libraries or to create new ones with your own user-defined spectra.
The following dedicated spectral libraries are provided by VUV.

Automatically Deconvolve Co-eluting Compounds
Let’s face it: Even with good chromatographic separation, compounds can coelute—especially with complex samples. The VUV Analyzer for Fuels provides a powerful and automated solution: Time Interval Deconvolution™ (TID™). TID works by slicing a chromatogram into regularly spaced time intervals, each with a unique summed absorbance spectrum. Each slice is then automatically analyzed to determine the contribution of each compound to the measured spectra. This means complex chromatograms can be easily, reliably deconvolved and analyzed, without the need for a fixed peak table.
