自主研发的小型高效气体纯化系统、二氧化碳激光熔样系统、流体包裹体提取系统和空气氩标定系统,与新一代小型高灵敏度多接收稀有气体质谱仪ArgusVI联机,建立了激光阶段加热~(40)Ar/~(39)Ar定年、真空击碎流体包裹体~(40)Ar/~(39)Ar定年和空气氩标定等分析测试方法。开放式Qtegra Noble Gas软件和外部设备控制器PeriCon,使用户能够方便地自主增减和控制外部设备,实现计算机自动控制。通过“触点闭合”方式,Qtegra软件触发国产二氧化碳激光加热熔样软件启动,两者协调工作,实现激光阶段加热~(40)Ar/~(39)Ar定年分析的实验流程全自动化。空气氩分析获得了非常稳定的~(40)Ar/~(36)Ar比值,展示了自制空气氩标定系统和小型纯化系统的卓越性能,可资借鉴。新建~(40)Ar/~(39)Ar实验室为开展油气成藏年代学研究提供了一个高精度的测试平台。 |

In this study we designed and developed an efficient preparation system of small volume, a CO_2 laser for heating samples, a crusher for extracting fluid inclusions and an air argon system for automatic ~(40)Ar/~(39)Ar dating. A new ~(40)Ar/~(39)Ar laboratory has thus been established by using these apparatus connected to an ArgusVI mass spectrometer in China University of Geosciences (Wuhan). The peripheral accessories of third party hardware, such as pneumatic valves, CO_2 laser and crusher, can be controlled by the Qtegra Noble Gas software through a PeriCon (peripheral controller). Therefore, the experimental precedures of air argon analyses, ~(40)Ar/~(39)Ar dating by laser stepwise heating and by crushing in vacuo could be fullly automatically performed. By two hundreds of air argon analyses, we have obtained well concordant atmospheric ~(40)Ar/~(36)Ar ratios with a weighted mean of 302.22 ± 0.03 (lσ, MSWD = 0.74),indicating that all the devices made in-house are effective and reliable. This work serves as a pioneer example in China for establishment of a new noble gas laboratory with home-made peripheral accessories except for mass spectrometer. |
