Specialty Gas
Gas chromatography is a key tool in the analysis of trace components in high purity gases used at pharmaceutical, electronics, petrochemical, food and beverage plants, and medical facilities, or in support gases for analytical instrumentation in laboratories and research facilities. Mixed gases are also carefully quantified to be used for the calibration of analytical or process instruments.
Known advantages of VUV Spectroscopy
- Provides real-time bulk and specialty gas data, enabling improved process control
- Blended gas samples can be analyzed with one detector that is not dependent on chromatographic separation
- Overlapping signals can be easily deconvolved using VUV software
- Improved sensitivity advantage of 100 – 1000X over FTIR
- Easy to understand analysis by Beer-Lambert Law (same principle used in UV-Vis spectroscopy)

Learn more about the SVGA-100 streaming gas analyzer. The SVGA-100 is the world’s first streaming gas detector using vacuum ultraviolet (VUV) spectroscopy for real-time quantitative analysis. Most chemical compounds absorb strongly in VUV absorbance wavelength range (120 – 240 nm). Photons in this region can produce electronic transitions in virtually all chemical bonds, especially in ground state to excited state transitions such as σ→ σ* and π→ π*. The result of being able to collect all of the electronic transition data is that every compound has a unique spectral profile in the VUV. The SVGA-100 is a universal detector with unmatched selectivity that is designed for real-time bulk and specialty gas monitoring with no need for prior chromatographic separation.
Solving Analytical Challenges in Specialty Gas
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
Spectral Identification

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
