| Abstract: | The oxygen and nitrogen contents in NiPt alloy were determined by pulse infrared absorption method and thermal conductivity detection method. The determination conditions, sample preparation, cleaning and sample weight of TC-400 oxygen and nitrogen analyzer were tested. The relative standard deviations (RSD, n=11) of oxygen were 5.08%-9.56%, and the recoveries were 95-107%. The nitrogen content is less than 0.001%, and the recovery rate is 96%~105%. The method can meet the requirements of production analysis. |
