摘要
介绍了一套用于惰性气体氙β-γ符合系统的进样装置。该装置较好地解决了惰性气体氙β-γ符合系统在进样方面存在的问题,使系统具备了四种氙取样设备归档样品的测试能力,同时还可以进行归档瓶体积和压力的测量,扩展了系统的功能,使系统具备了独立完成氙归档样品现有分析项目的能力。利用该装置准确标定了系统中气相色谱的标准曲线,通过与Agilent6890气相色谱进行测量比对,二者在3%内符合,检验了所标定的标准曲线的准确性。
It introduces an injection apparatus of noble gas xenon β-γ coincidence system. Some problems about sample injection of noble gas xenon β-γcoincidence system is solved. Four kinds of archive samples can be measured by β-γ coincidence system with this injection apparatus. The volume and pressure of archive sample can be determined by this apparatus. The calibration curve of gas chromatogram in β-γ coincidence system is obtained. Some samples are compared by β-γ coincident system and Agilent6890-type gas ehromatogram. The results are coincident within 3%.
