Flavors & Fragrances
Gas chromatography is commonly used in the analysis of a broad range of volatile compounds across a variety of functional groups to ensure product quality, provide competitive analysis, determine regulatory and environmental compliance, assess product adulteration, screen for possible toxic contaminants, and identify and quantify target allergens.
Known advantages of VUV Spectroscopy
- VUV AnalyzeTM provides a new tool for automating flavor and fragrance analysis
- Rich 3D data set: absorption vs. wavelength vs. retention time
- Spectroscopic deconvolution simplifies chromatographic separation challenges
- Enables chromatographic compression for higher analytical productivity
- Flavors & Fragrance isomers have distinct spectra and can be unambiguously differentiated
- Easy to understand analysis by Beer-Lambert Law (same principle used in UV-Vis spectroscopy)

Solving Analytical Challenges in Flavors & Fragrances
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

A summary of the VUV Analytics and Supelco Seminar tour covering the water analysis GC applications addressed by Watercol Columns & GC-VUV is included.
“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.”
