本文从富集原理及其在光谱超痕量分析的应用方面分别对这几种氢化物发生后的气相富集技术进行了较详细地综述。这些气相富集方法包括液氮冷却捕集技术、气球收集技术、石墨炉原位捕集技术、吸收液吸收技术及固体吸附技术等。并对这些氢化物气相富集技术的潜力 ,及与各种光谱分析法联用的发展前景也进行了讨论
In this paper, the principle of enrichment and its applications in spectral ultra-trace analysis of these hydride after gas phase enrichment technology were reviewed in more detail. These gas-phase enrichment methods include liquid nitrogen cooling and capturing technology, balloon collection technology, graphite furnace in-situ capture technology, absorption liquid absorption technology and solid adsorption technology. The potential of these hydride vapor phase enrichment technologies and the prospects for their development with various spectroscopic methods are also discussed
