Chemical compounds and their precursors can be unambiguously identified and quantitated by VUV spectroscopy. Solvents, water, and other analytes can be characterized in the same run, saving time and analysis complexity.
Known advantages of VUV Spectroscopy
- Provides both qualitative and quantitative characterization of target compounds along with their precursors and contaminants
- The capability of characterizing isomeric impurities without need for chromatographic baseline resolution
- Software deconvolution of analyte co-elution allows short GC chromatographic compression
- Intuitive data processing workflow and software automation remove analytical complexity
- Robust instrumentation with minimal maintenance needs
- Easy to understand analysis by Beer-Lambert Law (same principle used in UV-Vis spectroscopy)

Solving Analytical Challenges in Specialty Chemicals
Key Features of VUV Spectroscopy
- High degree of data analysis automation reduces human error
- Intuitive spectral fingerprint compound identification and Beer’s Law quantitation eliminates guesswork
- Software deconvolution of co-eluting analytes allows chromatography runtimes to be deliberately compressed
- Proprietary algorithms automate compound class characterization
Shining a new light in gas chromatography and streaming gas applications.
Everything absorbs strongly in the VUV spectrum. Compounds can be unambiguously identified and quantitated in a variety of applications including oil & gas, forensics, fragrances & flavors, petrochemical, environmental, and life science. VUV detectors provide unmatched selectivity of isomers and co-eluting analytes without the need for chromatographic baseline resolution. Unlike legacy detection methods, VUV spectroscopy allows for more automated analysis with lower risk of errors, shorter chromatography run times, and higher analytical throughput.
- Universal, yet selective detector with very sensitive spectral response
- Easy deconvolution and quantitation of co‑eluting analytes
- Robust technology with no reliance on vacuum pumps
- No calibration required – 1st principle detection technique provides a predictable linear response
- Complements mass spectrometry by fully characterizing isomers and compounds with low mass quant ions

This article in the Feb 2017 edition of The Column describes the results of a pilot study focused on trace water determination in common organic solvents using an ionic liquid stationary phase of GC column in a GC-VUV platform.
Characterization of Thermal Runaway Events in Lithium Batteries via Gas Chromatography – Vacuum Ultraviolet Spectroscopy
In this bulletin we demonstrate the use of a GC detector based on this short wavelength region, known as the vacuum ultraviolet (VUV) region, in the characterization of volatile gases evolved during thermal runaway events in lithium-ion and lithium-metal batteries.

James Diekmann describes smokeless gun powder analysis using a VGA-100 and Gerstel MPS2 autosampler with Solid-Phase Microextraction (SPME) capabilities. He discusses work to characterize a carryover compound detected in replicate injections.
“The VUV detector has proven itself with the ability to distinguish olefins and aromatics from aliphatics – that’s a killer application given the complexity and time involved using any other technique. The VUV detector’s ability to perform a more accurate and much more robust PIONA analysis is an important milestone in its ongoing success.”
