Nutraceuticals & Alternative Medicine
GC-VUV provides unambiguous identification and quantitation of alternative medicine contaminants and adulterants. Compounds are unambiguously identified and quantitated, and software automation makes data analysis accessible to users of all skill levels.
Known advantages of VUV Spectroscopy
- Provides both qualitative and quantitative characterization of alternative medicine and related 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)

Coeluting Peaks and VUV Absorbance Spectra – When a Little Means a LotJack Cochran, VUV Analytics

As a gas chromatographer using MS the coeluting-isomer problem didn’t bother me too much, as it allowed me to practice the art of separation. Inevitably though, critical compound separation leads to undesirable, longer GC run times, which brings us back to VUV and its uniqueness.
The VGA-101 is a next generation universal detector for GC with extended wavelength and higher allowable operating temperatures. It is intended to simplify complex applications with advanced capabilities including complete isomer identification, shorter GC run times, and resolution of co-eluting peaks.

“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.”
