Abstract

Using ARL’s 1.5 m quantometer, analyses of magnesium metals and its alloys have been carried out by the point-to-plane method.<BR>In magnesium metals, when low voltage spark (L=360 μH, C=60 μF, R=50 Ω, V=940 V) is used for excitation and the sample polarity is negative, the analytical results are obtained successfully.<BR>In magnesium alloys, when high voltage spark(L=360 μH, C=0.007 μF, R=residual, V=20 kV) is used for excitation, the analytical results are obtained successfully.<BR>Analysed elements and concentration ranges are Al 0.04∼0.22% and 5.3∼10.3%, Cu 0.006∼0.2%, Fe 0.004∼0.03%, Mn 0.01∼0.3%, Ni 0.0006∼0.03%, Pb 0.006∼0.13%, Si 0.01∼0.44%, Sn 0.005∼0.13%, and Zn 0.001∼0.15% and 0.11∼3.5%, and these elements are determinable with a coefficient of variation of about 1∼5%.
