✦ Synopsis

Field-ionization mass spectrometry, which produces fragmentation-free mass spectra, is being applied to the analysis of coal-liquefaction products. Using a new highly efficient and sturdy field-ionization source, samples of various coal-liquefaction products have been successfully analysed and their molecular-weight profiles determined by the integrating multiscan technique. The range of applications of this novel analytical technique to research and development of coal-liquefaction processes is discussed.
