| 摘 要： | 建立了脉冲熔融-飞行时间质谱法测定Nd-Fe-B材料中的氧、氮、氢的方法,在选定的实验条件下,氧、氮、氢的检出限分别为0.021,0.060,0.002μg/g;利用系列标准样品得到各元素的校准曲线,线性相关系数R2均大于0.99。将方法应用于Nd-Fe-B材料的测定,经对比实验验证,方法测定值与传统的脉冲熔融-红外/热导方法测定值相符合。

| Abstract: | An quantative method for the determination of O,N and H in Nd-Fe-B sample by pulsed melting time-of-flight mass spectrometry was established.Under the selected conditions,the detection limit of O,N and H is 0.021,0.060,0.002μg/g,respectively.The calibration curves for the three elements were obtained using a series of CRMs samples.All linear correlation coefficients R2 were better than 0.99.This method has been applied to analyze real Nd-Fe-B samples.The analytical results by the new method are consistent with those by the traditional pulsed melting IR and TCD（thermal conductivity detection）method. |
