X-ray fluorescence spectrometry is an analytical technique currently being used to measure the trace element concentrations of many elements in environmental samples such as particulate matter collected from urban aerosols and suspended matter in polluted water. The recent development of the dichotomous sampler permits collection of particulate matter and separation into a 0 to 2 ..mu..m range (fine particles) and > 2 to 10 ..mu..m range (coarse particles). Collection of these particles on thin membrane filters, which have a low trace element blank, provides samples, which are well suited for rapid x-ray fluorescence analysis, for elements with Z > 13 and sufficiently sensitive for monitoring applications. Quantitation is usually achieved by comparison of the x-ray emission intensities of the elements of interest with those from thin calibration standards.
