文摘

Demonstrate the measurement of EC and OC on Teflon filters using optical color space sensing system. Demonstrate the equivalency of Teflon and Quartz for EC and OC measurement by the optical color space method. Demonstrate that inorganic components of PM2.5 do not lead to bias in the optical color analysis of OC and EC. Evidence that different sources of OC have small optical differences using the optical color method that may be exploited.
