A multichannel wavelength x-ray fluorescence spectrometer, specially adapted for rapid analysis of air pollution particulate samples, is described. The system contains an array of fixed-wavelength spectrometers optimized for simultaneous analysis of 16 preselected elements and a computer-operated scanning channel for the determination of any number of additional elements. A loading device permits automatic handling of batches of up to 100 frame-mounted 47 mm filter samples. Instrument operation, data processing, and printout of results are controlled by a minicomputer. The system permits rapid elemental analysis at high spectral resolution, a significant advantage with air pollution samples which typically contain several dozen elements at a wide range of concentrations. For samples deposited on membrane filters, 100-second detection limits are in the range of 2 to 40 ng/sq. cm for most elements of interest.
