Using A R L's 1.5 m Industrial Research Quantometer, analyses of rare earth elements and zirconium in magnesium alloys have been carried out by the point to-plane method. High voltage spark discharge (L= 360 μH, C=0.007 μF, R=residual, V=20 kV) is used for excitation. Elements analysed and the range of their concentration are : La 0.061.4%, Ce 0.041.9%, Pr 0.160.5%, Nd 0.43.5% and Zr 0.7%, and these elements are determined with the coefficient in the variation of about 13%.
