Abstract:We investigated the simple and rapid preparation of standard materials of major and trace elements in aerosol particles for X‐ray fluorescence (XRF) analysis to study long‐range transport of air pollutants in East Asia. Standard materials for calibration curve were prepared using a small‐chamber sampling technique consisted of a 3‐L cylindrical acrylic chamber, aerosol filter holder, flow meter, and vacuum pump. Prepared aerosol standard materials had an excellent homogeneity in 0.5 mm × 0.5 mm analytical area… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
