GC-VUV Analyzer
A simple analyzer for complex matrice analysis
A unique solution for turnkey applications
GC-VUV: One Technology, Unlimited Capabilities
Vacuum UV (Vacuum Ultra Violet) is a unique spectral region of UV in which virtually all compounds absorb.
Why settle for complex multidimensional systems like the Reformulizer when you can achieve better results with a single-column GC? The VUV detector simplifies your laboratory workflow by providing robust data for PIONA Analysis (ASTM D8071), Jet Fuel Analysis (ASTM D8267), Diesel and Biofuels.
The GC-VUV is fully compliant with the most stringent international standards (ASTM, ISO, DIN) for hydrocarbons processes applications.

What does VUV technology bring you?
- Advanced Qualitative Analysis: Compounds and chemical families are identified with absolute certainty via their unique VUV spectral fingerprints.
- Unrivaled Selectivity: Achieve superior resolution for isomers and co-eluting analytes without the need for baseline chromatographic separation.
- Streamlined Quantitation: Benefit from a universal detector response based on the Beer-Lambert Law, with automated concentration calculations using integrated standards.
Operating Principle:
High-Energy Spectral Identification Vacuum Ultraviolet (VUV) light, characterized by high energy and short wavelengths, induces electronic transitions in virtually all gas-phase chemical bonds. This interaction produces VUV spectra that are highly specific to the chemical structure, reflecting the intrinsic absorption cross-section of every molecule.
Unique Spectral Fingerprints Each measured compound exhibits a unique spectral signature. Furthermore, compounds within the same chemical class share distinct spectral similarities. This unique property allows for the targeted and precise identification of compound classes in complex samples—making it the ultimate tool for PIONA analysis in fuels.
Purpose-Built for Precision The VGA-100 and VGA-101 detectors are specifically engineered for gas chromatography (GC) and gas flow analysis. They represent the pinnacle of detection technology for high-stakes laboratory environments.
The Power of Automated Deconvolution: One of the most significant advantages of the VGA series is its powerful deconvolution software. By leveraging unique spectral data, it eliminates the need for baseline chromatographic resolution: Co-eluting analytes are accurately identified and quantified, Isomers are easily distinguished. Unlike traditional multi-column, valve-based GC systems (such as the Reformulizer), VUV deconvolution simplifies the hardware setup while delivering more reliable data in less time.
With its ability to resolve the most challenging matrices, the GC-VUV has become the preferred solution for analyzing fuels and other complex hydrocarbon mixtures.
