Food & Beverage Safety
Food and beverage manufacturers regularly test for process and quality control, screening of adulteration, identification of origin, quantification of additives, as well as general flavor and palatability using gas chromatography. Driven by the need for health and nutritional safety, national and international regulations also require that food and beverage manufacturers screen their products for contaminates such as pesticides, environmental pollutants, toxins (either from spoilage or micro-organisms), veterinary drugs, and possible packaging material leaching.
Known advantages of VUV Spectroscopy
- Class identification for simplified and more accurate analysis of MOSH / MOAH fractions
- Isomeric analysis ranging from cis- and trans-fatty acid analysis to complete lipid profiling
- Faster and more automated vegetable and seed oil screening
- Broad component screening of tobacco deeming analytes in e-cigarettes
- Reduces test methods needed for characterization and allows for chromatographic compression

Solving Analytical Challenges in Food & Beverage Safety
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

“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.”
