国内稀有气体同位素分析技术主要应用于分析天然气和固体矿物样品。原油样品采集易受空气污染，并且挥发性有机组分严重影响分析结果。本实验利用压力差设计了一种顺压采样器，以排除空气；采用真空－超声波脱气；通过两级纯化系统，实现溶解气活性组分的完全去除，降低对超高真空仪器Noblesse的污染。结果表明：原油脱气效率达99．5％以上；同位素分析的相对标准偏差＜6．10％。顺压采样器及两级纯化系统的提出，实现了原油稀有气体分析。

Rare gas isotope analysis technology is mainly applied to the samples of natural gases and solid minerals .Crude oil sample is easily polluted by air ,and volatile organic components seriously influ‐ence the analytical results .We designed a new sampler to eliminate air pollution ;vacuum‐ultrasonic tech‐nology was used for crude oil degassing ;two levels of purification system can remove the active gas compo‐nents ,and reduce the pollution of the ultra‐high vacuum apparatus‐Noblesse .T he results show ed that the crude oil degassing efficiency was above 99 .5% ; relative standard deviation of isotope analysis w as <6.10% .
