Popis:	A reflectance method for the determination of the elemental carbon component of soot in atmospheric fine particulate matter collected on a filter has been developed. Two instruments are described. One operates continuously as the aerosol sample is being collected, measuring the decrease in reflectance of light from the filter spot through which air is aspirated. The other instrument measures the reflectance of samples mounted after a collection on a filter. The instruments have been calibrated with soot standards of known total non-volatile carbon content determined by the GRALE technique after heating. Limited field data are presented on both the total carbon and soot carbon content of the St. Louis urban fine aerosol.
