Optimum operating conditions of a coherent forward scattering resonance monochromator (CFSRM), such as applied magnetic field strength, pulse duration, and peak current of pulsed glow discharge atomizatlon, were studied. Correction of performance-limiting factors, such as leakage of the crossed polarizer and analyzer, was tried by two different methods. One used the time dependence of atomic vapor density produced by pulsed glow discharge atomizatlon and the other used magnetic field modulation. In the present apparatus, the method using time dependence of atomic vapor density was superior. Experiments to obtain the rejection of continuum background and neighboring lines of copper resonance lines (324.8 and 327.4 nm) in emission spectra were performed, and satisfactory results were obtained.
