During this period pressure programming techniques for the capillary supercritical fluid chromatograph (SFC) were examined and applied to the analysis of polystyrene oligomer samples as well as polycyclic aromatic hydrocarbon (PAH) extracts from a carbon black sample. Cross-linking procedures for insoluble non-polar stationary phases were evaluated to determine relative merits of various cross-linking agents and techniques. The second SFC instrument was constructed and interfaced to a microcomputer for control of the UV detector as well as for control of pressure programming.
