Yc. Chan et al., APPLICATION OF PIXE ANALYSIS TO URBAN AEROSOL SAMPLES COLLECTED ON WHATMAN-41 FILTERS, International journal of environmental analytical chemistry (Print), 68(1), 1997, pp. 33-45
The applicability of the Proton Induced X-Ray Emission (PIXE) techniqu
e to multi-elemental analysis of PM10 aerosol samples collected on Wha
tman 41 cellulose fibrous filters is investigated using concurrent sam
ples collected on teflon membrane filters as references. The elemental
levels measured on the two types of filter samples are highly correla
ted and the ratio of the elemental levels is related to the deepness o
f penetration of particles inside the filter, which is calculated from
the Fan Filter Model. Therefore, PIXE analysis can be used to describ
e urban aerosol samples collected on low impurity level porous filters
such as Whatman 41.
