Filter Absorption Correction for X-Ray Fluorescence Analysis of Aerosol Loaded Filters
Published online by Cambridge University Press: 06 March 2019
Abstract
In the case of X-ray fluorescence analysis of aerosol loaded filters, the X-ray absorption effect Is due to particulate matter absorption and to filter material absorption. The latter contribution is of a predominant importance in many practical cases. It can be calculated from the ratio of the X-ray intensities measured from the front and back side of the filters. The sandwich geometry obtained by folding the filters in two with the loaded side inwards during the measurement renders the filter material absorption correction much simpler and often more accurate, and offers distinct additional advantages.
