Characterization of Nitrogen-Containing Species in Coal- and Petroleum-Derived Products by Ammonia Chemical Ionization High-Resolution Mass Spectrometry
A coal-derived light distillate and a petroleum-derived residuum have been studied by high-resolution mass spectrometry using both low-pressure ammonia chemical ionization and low-voltage electron impact ionization. A mass calibration mixture for use with ammonia chemical ionization has been develop...
