A technique for simultaneous multielement analysis based on a scanning Fabry-Perot interferometer and atomic emission is described. Detection limits are determined for various common elements using the oxygen-hydrogen flame as a test case. The results show that semitrace to trace levels in solution can be analyzed. This technique is limited to groups of elements which contain relatively few total emission lines in a certain wavelength region. Spectral interference can, in general, be eliminated by the proper choice of the interferometer spacing. Analysis of tap water and parameters essential to this optical scheme are discussed. The main advantages of this technique are the high luminosity and the ability to perform analysis in the millisecond time scale. (auth)
