| Abstract: | An inert gas fusion-infrared absorption method for the determination of oxygen in Pr-Nd-Dy by was investigated. A graphite crucible and a highly pure nickel basket were used in the testing experiment. 0.1 g real sample was analzed at the analysis power of 4 500 W and the resutls were satisfactory. The experimental results showed that the sample was completely released. The relative standard deviation （RSD, n = 5） was 1.9%. The spiked recovery experiment was conducted with GSBH40104--1996 standard samples Go（O） /%=0. 009 43） and the recoveries were determined as 95%-108%. |
