The use of LiChrospher and LiChrosorb to obtain profiles of molecular weight distributions is shown for some petroleum crudes, pitches, and asphaltenes. The elution time was less than thirty minutes, and data were obtained on less than 16 ..mu..g of sample.

By utilizing a mercury pressure valve, a volatile solvent, n-pentane, was conveniently used in a classical gravity-feed liquid chromatographic column. The pseudo-closed system maintained column efficiency by preventing the formation of column bubbles. The system was efficient in reducing solvent evaporation as well as preventing water condensation at the column outlet. Since free solvent vapors were eliminated, the system provided an additional safety factor when a flammable solvent, such as n-pentane, was employed. While the columns were used for solvent cleanup, a small modification would transform the system into a solute purification apparatus.

The ORR operated at an average power level of 29.2 Mw for 23.6% of the time during January, February, and March of 1977. Six fuel elements were declared spent (56.3% burnup) during the quarter, while five new elements were placed in service. The reactor was shut down on seven occasions, none of which were unscheduled. Reactor downtime needed for refueling, maintenance and checks was quite low, with the reactor remaining available for operation 87.0% of the time. Maintenance activities, both mechanical and instrument, were essentially routine in nature.

Glass beads containing rubidium or cesium can be prepared from either laboratory glass or synthetic glass mixtures. The sensitivity in the nitrogen-phosphorus mode was highest when the Na/sub 2/O/B/sub 2/O/sub 3/ ratio was larger than unity or when there was a high rubidium or cesium concentration. Beads containing no sodium showed the lowest noise and greatest stability. Linearities ranged from 3 to 11 x 10/sup 3/. Detectabilities of 40 to 70 x 10/sup -13/ g/sec and 1.5 to 8 x 10/sup -13/ g/sec were typical for azobenzene and malathion, respectively, in the N-P mode. In the phosphorous mode, the corresponding detectabilities were 20 to 8900 x 10/sup -13/ g/sec and 1 to 120 x 10/sup -13/ g/sec.

Studies completed during the past year were: pressure and temperature effects on retention behavior of ion pairs, fractionation studies of sulfur isotopes in carbon disulfide, anomolous peak shapes obtained in gas chromatography using liquid crystal stationary phases in an electrostatic field, and the application of a new steric-exclusion packing for molecular-weight fractionation of petroleum crudes. Studies are continuing on the effects of the dead volume of a detector on the peak shape as a function of flow rate and molecular weight of the solute and on basic studies relating to the optimization of chromatographic parameters in supercritical fluid chromatography of large molecules, especially polymers. New studies that have been initiated include: the fractionation and identification of vanadium species in crude oils, the study of recycling chromatography at elevated pressures for difficult separations such as those involving isotopes, and the application of gradient techniques in liquid chromatography for the fractionation of polymers. Finally, equipment has been ordered for making solubility studies relating to the precipitation of compounds from geothermal brines, but experiments have not yet begun.

The ORR operated at an average power level of 29.3 Mw for 20.1% of the time during October, November, and December of 1976. The operating time is low due to the reduction of operating time to a level compatible with funding. Six fuel elements were declared spent (57.6% burnup) during the quarter, while no new elements were placed in service. The reactor was shut down on seven occasions, one of which was unscheduled. Reactor downtime needed for refueling, maintenance and checks was quite low, with the reactor remaining available for operation 92.0% of the time. Maintenance activities, both mechanical and instrument, were essentially routine in nature.
