Pyrolysis mass spectrometry has been performed by photoionization with coherent vacuum ultraviolet (VUV) radiation. Pyrolysis mass spectra are often difficult to interpret owing to the complex distribution of ions formed. Much of this complexity can be ascribed to the heterogeneity of samples typically analyzed or to the numerous reaction pathways accompanying pyrolysis. Indeed, information of this type is often the goal of a pyrolysis experiment. However, fragmentation induced by the ionization process can also be extensive and often obscures useful information, VUV photoionization with 9.6 to 10.5 eV radiation minimizes fragmentation by photoionizing just above the ionization threshold.
