四极质谱定量分析方法研究所关心的是被分析样品中的(而不是质谱分析室中)各组分气体的分压强判断,引用质谱分析系统“综合相对灵敏度系数α”这一概念,就无须校准质谱计对各种气体的 S 值。α值的测定简便易行、精度稳定良好,易于控制。它可对“特征峰”进行相当精确的补偿(即修正)。质谱分析工作者关心的应是被分析样品中组分气体的分压强(在绝大多数情况下,分析室的绝对压力总远远小于被分析样品的绝对压力)。
The quadrupole mass spectrometry method is concerned with the determination of the partial pressures of the components in the sample being analyzed (rather than in the mass spectrometry chamber). The concept of the “comprehensive relative sensitivity coefficient α” of a mass spectrometry system does not require Calibrate the mass spectrometer for various gas S values. The determination of α value is simple and easy, the precision is stable and easy to control. It compensates (ie corrects) the “characteristic peak” fairly accurately. Mass spectrometry workers are concerned with the partial pressure of the component gas in the sample being analyzed (in the vast majority of cases, the absolute pressure in the analysis chamber is always much less than the absolute pressure of the sample being analyzed).
