Extensive annual maintenance was performed on the mass spectrometer and ancillary equipment. The technique of micromolecular probe distillation-FI/MS was applied to the characterization of petroleum heavy ends. In this regard, the available standards for converting ion time centroids to ion m/e values in the high m/e region is inadequate. Development of a computer method for assigning most probable formulas to precise ion masses was completed. Considerable progress was made in preparing three manuscripts describing the method. The initial phase of a project which attempts to predict relative FI sensitivities from molecular parameters was completed. The effort to develop FI/MS as a technique for analyzing saturate hydrocarbons was extended to encompass total crude oils and the saturate fractions isolated from them. Preparation of publications describing our extensive characterization of the oils and asphaltenes from a COED coal liquid were essentially completed. The presence of numerous aromatic compounds containing two nitrogens in an anthracene oil was demonstrated. Characterization of an SRC-II coal liquid was initiated.
