Detailed measurements of organic compounds coupled with accurate thermodynamic models that explain gas particle-phase relationships are necessary for measuring different aerosol compositions in various environments. Carbon, a large component of PM 30 to 40 percent , is often divided into several fractions, most commonly organic carbon and elemental carbon. Elemental carbon, the black, light-absorbing fraction, is measured by many.
Some of the more detailed carbon fractions have been found to represent different source contributions Chow et al. Fung et al. This comparison showed that different carbon analysis methods can vary markedly as a function of the composition and concentration of the sample. Both protocols sample air through quartz-fiber filters. Punches from these filters are then submitted for analysis Chow et al.
The two methods differ in terms of combustion temperatures, analysis durations, and optical monitoring. When the cross-sections of the filter punches were examined: 1 charring was found throughout the filter, either from adsorbed organic vapors during sampling or adsorbed vaporized particles during analysis or liquid organic particles; 2 elemental carbon near the filter surface evolves earlier than some of the charred organic carbon embedded in the filters during thermal analysis; and 3 charred organic carbon attenuates red laser light more efficiently than elemental carbon Chow et al.
Many operating parameters can individually or collectively cause variations of up to 30 percent in test results. These include differences in combustion atmospheres, temperature ramping rates, and temperature plateaus. Unfortunately, no systematic research is being done to resolve these discrepancies.
Such research should include: 1 a review and evaluation of the published literature, much of which is not in the air-quality journals; 2 documentation of the method used, especially for thermal evolution carbon comparisons with different combustion temperatures, residence times, ramp rates, and optical-pyrolysis corrections; 3 establishment of standards for different sources of black carbon e.
