| Abstract: | This paper studies the determination method of carbon and sulphur in rare earth metal and oxide by infrared-absorption method.When sample is combusted in high freqency furnace,carbon and sulphur are given off and detected in the form of carbon oxide and sulphur oxide.The value of RSD% is less than 10%.The recovery of carbon and sulphur is 88%~108% and 89%~110%,respectively. |
