During the Pittsburgh Air Quality Study (PAQS) an automated semi-continuous thermal-optical transmittance (TOT) carbon analyzer was used to measure 2–4 h average particulate organic (OC) and elemental carbon (EC) concentrations from July 1, 2001 to August 13, 2002. To minimize the adsorption of vapor-phase organics, the sample air was drawn through a multi-channel parallel-plate diffusion denuder placed upstream of the carbon analyzer. Particulate OC and EC in the sample air were then collected… CONTINUE READING
