Abstract

Helium is a typical carrier gas for GC-MS systems and is a limited and valuable material. Here, we introduce alternative gas analysis technologies that utilize hydrogen and nitrogen. When hydrogen is utilized in a GC-MS system, it is more sensitive and has better separation than nitrogen. On other hand, in the case of nitrogen, it is easier to handle as compared to hydrogen. In this paper, basics gas chromatography is explained, and the gas analysis technologies using hydrogen and nitrogen as an alternative to helium gas are described. These technologies will contribute to reducing the consumption of helium.
