一、前言 六十年代初,国外提出了从测质谱计绝对灵敏度S入手进行定量分析的实验校准方法[1],它是用真空计量校准的办法来测定S值的,这在工厂难以做到,关键是这样测得的S值精度差,难以实现符合精度要求的分压强测量。经过探讨,我们提出了一种实验校准的方法,它的显著特点在于回

I. Preface In the early 1960s, the foreign countries proposed an experimental calibration method [1] that started with quantitative sensitivity analysis of mass spectrometer [1] and measured the S value by vacuum calibration, which is difficult to achieve in the factory , The key is that the S value measured in this way has poor accuracy and it is difficult to achieve the partial pressure measurement that meets the accuracy requirements. After discussion, we propose a method of experimental calibration, its salient features lie back
