ＭＭ５４００静态真空质谱仪是国际同类产品中的先进型号，代表着２０世纪９０年代后期的水平，可用于两个重要的研究领域———氦同位素分析和氩同位素分析。氦同位素分析结果可用于天然气成因判别和构造地质学及大地热流方面的研究。天然气中几乎都含有氦。在氦的两个稳定同
The MM5400 Static Vacuum Mass Spectrometer, an advanced model of its kind in the world, represents the level of the late 1990s and can be used in two important areas of interest - helium isotope analysis and argon isotope analysis. Helium isotope analysis results can be used for natural gas genetic discrimination and tectonic geology and heat flow research. Natural gas contains almost all helium. The two stable in helium are the same
