Gas chromatography – vacuum ultraviolet (GC-VUV) spectroscopy is a new technique that monitors molecular absorbance from 125-430nm. This range allows for unique spectral fingerprinting, isomer differentiation, and identification of known coeluting compounds. GC-VUV is an excellent hybrid between flame ionization detection (FID) and mass spectrometry (MS), providing the ease of use of FID and powerful selectivity of MS. In addition, VUV can detect compounds like water that are challenging for other detectors. This lends itself as a useful alternative to techniques like Karl Fischer titration. The extended wavelength range beyond 240nm also allows for selectivity of polycyclic aromatic hydrocarbons (PAHs) and other compounds that absorb in this region. This webinar will showcase examples of the unique features of this new detector, including GC-VUV’s ability to deconvolve coelutions for volatile compounds in a blood matrix, accurately detect and quantitate water, and selectively detect PAHs in complex matrices such as engine oil and diesel.
