Method for measuring content of trace impurities in nitrous oxide

The invention relates to the field of analysis and detection, in particular to a method for determining the content of trace impurities in nitrous oxide. According to the method for determining the content of trace impurities in nitrous oxide, a solution absorption method is used, absorption and enrichment can be carried out through the absorption liquid in the gas washing bottle, and the content of corresponding elements in a sample is directly determined through a mass spectrometer. The problem that in the prior art, a detection method is not easy to accurately quantify the content of metal impurities is solved, the detection precision is improved, and the detection cost is reduced. 本发明涉及分析检测领域，尤其涉及一种氧化亚氮中痕量杂质含量的测定方法。本发明提供的氧化亚氮中痕量杂质含量的测定方法，使用溶液吸收法，能够通过洗气瓶中的吸收液进行吸收和富集，使用质谱仪来直接测定样品中相应元素的含量。解决了现有技术中存在的检测方法不容易对金属杂质的含量准确定量的问题，提高了检测精度，降低了检测成本。
