Abstract: Vacuum ultraviolet absorption spectroscopy (VUV) continues to solidify its role in the gas chromatography (GC) detector pantheon. The VUV detector measures absorbance from 130 – 420 nm. In the low wavelength range, virtually all chemical compounds absorb and have unique absorption signatures. Numerous examples of the advantages of GC-VUV have been demonstrated in a variety of applications. These include the ability to easily deconvolve coeluting analytes, to distinguish isomeric species, to rapidly classify compositions in complex mixtures, and to directly quantify analytes based on pseudo-absolute determination principles. GC-VUV has been applied for analysis of fuels, flavors & fragrances, pharmaceuticals, and pesticides, among other GC-amenable analyte classes. Further, theoretical computations add another dimension for spectral prediction, not generally available for other GC detectors. Overall, VUV is capable of both reliable qualitative and quantitative analysis, and it is highly complementary to mass spectrometry in terms of the information it can provide. Advances and applications of GC-VUV to date will be presented in this talk.
