Calibration Research of Noble Gas Analyser and Its Uncertainty Evaluation Example

稀有气体分析仪是一类用于分析特定环境下稀有气体浓度的仪器。基于稀有气体分析仪的原理及应用,提出了校准过程中应满足的试验条件及主要技术指标,开发了示值误差、重复性、响应时间和报警功能的校准方法,并选取典型样品进行了试验论证,对测量过程的不确定度进行了分析。结果表明所提出的指标及校准方法切实可行。

Noble gas analyser is a type of instrument used to analyze the concentration of noble gas in specific environment. The requirements for experimental condition and technical indicators are made based on the principle and application. Also, calibration methods for items including error of indication, repeatability, response time and alarm function are proposed, typical sample is selected for experimental demonstration, and the uncertainty of the measurement process is analyzed. The results show that the proposed index and calibration method are feasible.
