VUV Analytics SVGA-100 Analyzer

VUV Analytics has made possible using absorption spectroscopy in the Vacuum Ultraviolet region, a spectral region of great interest hitherto reserved to synchrotrons. In this region of the spectrum, in the range between 120 and 240 nm, many organic compounds exhibit a strong absorption due to electronic bond transitions prohibited at higher wavelengths typical of near ultraviolet and visible light. The photons associated to Vacuum Ultraviolet (VUV) present energy such as to induce electronic transitions in virtually all molecules involving the states σ → σ * and π → π * thus making even simple alkanes detectable. The ability to record a spectrum attributable to these electronic molecular transitions therefore allows us to uniquely recognize molecules and classes.
The SVGA-100 streaming gas analyzer allows continuous monitoring and real-time measurement of gas purity in the VUV wavelength range from 120 nm to 240 nm without using a gas chromatograph. The absorption spectra are specific to each compound and provide unprecedented selectivity. The SVGA-100 analyzer is ideal for real-time analysis of gaseous compounds in which relatively equivalent concentrations or analytes absorbed in
