The application base of vacuum ultraviolet spectroscopic detection for gas chromatography (GC-VUV) continues to expand. GC-VUV is applicable anywhere that GC alone is applicable, and it provides qualitative information that is highly complementary to mass spectrometric detection. That said, data treatment is actually simplified given the unique and additive nature of absorption spectra from 120 to 240 nm.
Unique spectra based on the electron shape of a molecule can be obtained to allow differentiation of a large variety of isomeric components and classes.
Less emphasis is needed on chromatographic method development, since co-eluting species can be easily deconvolved. For both isomer differentiation and deconvolution, spectral similarity can be measured and considered to predict and understand method performance in various applications.
Several applications like oil-to-oil correlation based on aromatic profiles, cis/trans differentiation of fatty acids, water determinations in organic streams, isomeric differentiation of designer drugs and VUV selectivity of small industrial oxygenates will discussed in correlation to FID and mass spectrometry detection.
