VUV SPECTROSCOPY: SCIENCE IN A NEW LIGHT

VUV Analytics’ vision is to enable new science and better processes by harnessing the unique capabilities of VUV technology. VUV Analytics manufactures universal vacuum ultraviolet (VUV) spectroscopic detectors that provide a new dimension of chemical analysis accuracy. VUV light creates unique spectral signatures in the gas phase that result in unambiguous compound identification and quantitative analysis across a wide spectrum of complex applications. Unlike legacy GC detectors, VUV detection delivers scalable data analysis automation with reduced analytical error and higher analytical throughput. VUV detectors are designed for gas chromatography and streaming gas applications.

Everything absorbs strongly in the vacuum ultraviolet portion of the ultraviolet spectrum (120 – 240 nm) measured by VUV detectors. The high energy, low wavelength VUV energy produces electronic transitions in virtually all chemical bonds in the gas phase including ground state to excited state σ→ σ* and π→ π*. VUV spectra are specific to chemical structure and reflect the inherent absorbance cross section of individual compounds. VUV detectors provide unmatched selectivity of isomers and co-eluting analytes without the need for chromatographic baseline resolution.

WHAT MAKES VUV DETECTION DIFFERENT?

Superior analyte identification and quantitative analysis accuracy

>VUV spectral fingerprints are unique and specific to chemical compound structure >Closely related isomers can be spectrally differentiated >Spectral deconvolution ensures accurate quantitation of co-eluting analytes.

Universal detection that solves common GC separation problems

>GC runtimes can be significantly reduced through flow rate enhanced chromatographic compression and by resolving co-elution with VUV spectral deconvolution. >Complements mass spectrometry by fully characterizing isomers and compounds with low mass quantitation ions >Compound class analysis provides new tool for characterizing samples in complex matrices
