Abstract
Speciation results from earlier methods of quantitative analysis of TSP, dichotomous, and PM10 filters for compounds by XRD were often marginal to unacceptable because of very light loadings and the interfering effects of substrate fibres in cases of ultrasonic extraction and concentration. A method for analysis of very lightly loaded PM10 filters has been developed, using ultrasonic particle stripping, X-ray transmission of unloaded blank filters, substrate diffraction X-ray analysis, and mass absorption balance, along with the usual X-ray diffraction scanning. Analysis of a set of filters having less than 105 μg m cm−2 sample load is used to illustrate the improved procedure.
