“…The baseline resolved result at the bottom right of Figure 5 (94 ± 1% fossil), is a very recent datum that was achieved by the offline GC/AMS technique where the influence of the baseline was essentially eliminated through the special pre-purification technique of PAH ring size fractionation (Wise et al 1977;Pearson et al 1997). Two very important conclusions derive from this work.…”

“…A principal observation is that the initial 14 C result for benzo(ghi)perylene has a large uncertainty, due to the large "unresolved complex mixture" (ucm) of unknown isotopic composition that coeluted and was recovered in trap-6, the B(ghi)P trap. The vastly improved result showing 94 ± 1% fossil carbon was achieved through an improved purification technique involving the isolation of PAH ring size fractions (Wise et al 1977;Currie et al 1999a). ada and the singular enhancement of biomass burning aerosol carbon at Summit, Greenland on 5 August 1994.…”

ABSTRACT.A review is given of some critical events in the development of radiocarbon aerosol science, and the profound influence of radiocarbon accelerator mass spectrometry (AMS) on its current applications and future prospects. The birth of this discipline occurred shortly after the initial development of 14 C dating. Unlike dating, which is founded on the continual decay of 14 C and the resulting full range of 14 C/ 12 C ratios in once-living matter, 14 C applications to atmospheric aerosol research relate primarily to the determination of mixing ratios of fossil and biomass components. Such determinations have come to have major importance in work ranging from the resolution of woodburning and motor vehicle components of urban particulate pollution, to the apportionment of radiation-forcing (black) particulate carbon from natural wildfires and anthropogenic regional plumes. The development of this area has paralleled that of AMS itself, with the one or the other alternately serving as the driving force, in a sort of counterpoint. The remarkable million-fold improvement in sensitivity made possible by AMS has become critical in meeting rapidly emerging societal concerns with the origins and effects of individual carbonaceous species on health and climate.

“…A third method of chemical fractionation now being evaluated utilizes high performance liquid chromatography and is based on the method described by Wise et al (1977). With this technique, the undiluted sample or the sample in a hexane or hexane:methylene chloride solvent is loaded onto a normalphase NH2 column.…”
