摘要
核爆炸产生多种稀有气体核素,这些核素可作为核泄露监测对象。气相色谱是组分分离的重要手段,在核爆炸监测取样中有重要应用。本文以5分子筛作为固定相,高纯氮作为流动相,测量了氩、氪、氙、氡在气相色谱中的分离效果。结果表明,在相同色谱条件下,氩、氪分离度小于氪、氙分离度;在柱流量35.6mL/min、柱温353K条件下,气相色谱氩、氪,氪、氙,氙、氡分离度均大于2.25。
Radio-isotopes of noble gas,which are produced during nuclear explosion,can escape into atmosphere easily.These isotopes can be measured as good indicators for nuclear explosion.Noble gas monitoring,including sampling,measurement and analysis,became more and more essential.Gas chromatography is an important technology on noble gas separation during gas sampling.In this paper,while 5 molecular sieve was utilized as column stationary state and high-purity nitrogen as column fluid state,resolutions of argon,krypton,xenon and radon were widely investigated under different chromatograph conditions.As a result,the resolution of krypton and argon is less than the resolution of xenon and krypton;when column flow rate is 35.6 mL/min and oven temperature is 353 K,all of the resolutions of radon and xenon,xenon and krypton,krypton and argon are more than 2.25.
