A recently developed novel intense rare-gas excimer vacuum ultraviolet (VUV) light source, the electron beam-pumped excimer lamp (EBEL), has been applied to the soft single-photon ionization (SPI) of organic molecules in a compact orthogonal acceleration time-of-flight mass spectrometer (oaTOFMS). The SPI-oaTOFMS system was applied to the on-line monitoring of tobacco smoke. With this setup, it was possible to analyze the composition of individual puffs of cigarette smoke. Furthermore, a gas chromatograph (GC) was coupled to the EBEL SPIoaTOFMS system. Soft photo-ionization represents an additional separation dimension. By combination of the gas chromatographic and the soft-ionization mass spectroscopic separation dimensions, a truly multidimensional comprehensive analytical method could be derived.
