摘要

The following activities in regard to the development of micromolecular probe distillation in combination with field-ionization mass spectrometry (FI/MS) for quantitative analysis are reported. The temperature-control module for the direct-introduction probe was received and successfully interfaced to both the probe and the NOVA 3/12. Both temperatures and FI/MS data were minicomputer acquired for probe distillation of a 19component synthetic blend, a asphaltene-acid fraction,and the base fraction from an anthracene-oil sample. The acquired temperatures and FI/MS data for the 19component blend were processed on the IBM 370/158to obtain a quantitative distribution which is in excellent agreement with both the known composition and the one obtained from the FI/MS data acquired using the batch-inlet system for sample introduction. Development of algorithms for correlating the acquired temperatures with the acquired FI/MS data using the NOVA 3/12and for preparing the correlated data for remote job entry to the IBM 370/158were initiated. The DS-50S data acquisition system/CEC 21-110B double-focusing mass spectrometer combination was extensively utilized to acquire (1) sensitivities for field ionization of saturates and aromatics, (2) FI/MS data for determining the weight percents of the individual homologs present in the aromatic fractions from the oils and asphaltenes isolated from a COED liquid, (3) FI/MS data for the quantitative analysis of GPC fractions obtained from separation of a hydrotreated shale oil,and (4) FI/MS data for the molecular-ion group-type analysis of saturate fractions from petroleum and shale oil.
