Introduction
Gas Chromatography - Vacuum Ultraviolet (GC-VUV) spectroscopy is a recent innovation introduced in 2014 as a universal detection platform for gas chromatography1. The vacuum ultraviolet (VUV) absorbance spectrum measured by VUV detectors (120 - 240 nm) had historically been restricted to bright source synchrotron facilities due to significant background absorption challenges inherent to working within the wavelength range. The VGA-100TM GC-VUV detector is the first bench-top spectrometer capable of full VUV spectrum detection, and the VGA-101TM extends its wavelength detection range to 430 nm. Both VUV spectrometers have the unique capability of providing spectral information that is both qualitative and quantitative for most gas phase compounds.
