The system consists of a continuum xenon arc lamp source, a chopper, an argon-separated separated air/acetylene flame atomizer, a high-throughput, medium-resolution grating monochromator under Apple II+ wavelength control, a photomultiplier detector, and a photon counter with an Apple II+ for data collection and statistical treatment. The computer-controlled system is shown to give semiquantitative results (within ±50%) for 19 elements at two wavelengths each (one wavelength for 7 elements) in less than 15 min; quantitative results (within ± 5%) for each element at a selected wavelength were obtained in about 5 min. The system was characterized by determining 10 and 14 elements in synthetic mixtures and by determining a number of elements in NBS standard reference materials (orchard leaves and two steels).
