AB  - Comprehensive multi-dimensional hyphenation of a thermogravimetry device (i.e. a 
      thermobalance) to gas chromatography and single photon ionization-time-of-flight 
      mass spectrometry (TG-GCxSPI-MS) has been used to investigate two crude oil 
      samples of different geographical origin. The source of the applied vacuum 
      ultraviolet radiation is an electron beam pumped rare gas excimer lamp (EBEL). 
      The soft photoionization favors the formation of molecular ions. Introduction of 
      a fast, rapidly modulated gas chromatographic separation step in comparison with 
      solely TG-SPI-MS enables strongly enhanced detection especially with such highly 
      complex organic matrices as crude oil. In contrast with former TG-SPI-MS 
      measurements, separation and identification of overlying substances is possible 
      because of different GC retention times. The specific contribution of isobaric 
      compounds to one mass signal is determined for alkanes, naphthalenes, alkylated 
      benzenes, and other compounds.
