Specialty Chemicals

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

Featured Spectra

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
  • A non-destructive technique that compliments mass spectrometry

  • “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.”

  • “One of the main advantages of VUV detection for us appeared to be the ability to gain more specific molecular information…co-elutions that we know exist but cannot be identified with FID can be unraveled.”

  • “One thing that I really like about VUV is that it can be considered a universal detector but with the advantage of being familiar to us. We all used UV spectrometers in school.”
