脉冲熔融-飞行时间质谱法测定钛中氦和氩

应用气体分析仪开展脉冲熔融-飞行时间质谱法定氦的方法研究和定氩的应用研究，采用气标标定，标定曲线线性良好。选择脉冲-热导法作为参比方法，文中公布的实验结果均为两种方法对比数据。建立了质谱定氦和氩的方法，分析测定科研用充氦钛膜中氦，实际应用于测定粉末冶金钛合金中氩。试验表明脉冲熔融-飞行时间质谱法可以准确测定金属中氦和氩，定量分析结果与现有的脉冲-热导法基本一致。

Determination of helium and argon in titanium by pulse heating-time of flight mass spectrometry

Gas analyzer was used for the method study of determining helium and application study of argon by pulse heating-time of flight mass spectrometry. The linearity of calibration curves was good if standard gas was used. The pulse-thermal conductivity method was used as reference. The experimental results were comparison results of the two methods. The determination method of helium and argon was established. The helium in helium-filled titanium film for scientific research was analyzed, and the argon in titanium alloy for powder metallurgy was determined. The test results indicated that, pulse heating-time of flight mass spectrometry could be used for accurate determination of helium and argon in metal. The quantitative analysis results were consistent with those obtained by existing pulse-thermal conductivity method.
