中国地质大学（武汉）新建了一个配备Thermo Scientific© ARGUS VI质谱仪的全自动40 Ar/39 Ar实验室。我们设计并开发了一套小型高效制备系统（80 mL）、一套用于加热样品的CO2激光器、一套用于提取贫钾矿物中流体包裹体的破碎机以及一套储气罐（31 L）和移液管（0.1 mL）系统。ARGUS VI质谱仪由Qtegra Noble Gas软件操作，该软件可通过PeriCon（外围控制器）控制外围附件，如气动阀、CO2激光器和破碎机。大气氩分析、激光分步加热~（40）Ar/~（39）Ar定年和真空分级粉碎定年等实验过程可全自动进行。大气~（40）Ar/~（36）Ar比值的加权平均值为302.22±0.03（1σ，MSWD= 0.74，n =200），说明储气罐和吸管系统以及整个仪器系统是非常稳定的。该实验室是国内利用自制的质谱仪外配套设备建立新型惰性气体实验室的成功典范。
A new fully automatic40Ar/39Ar laboratory with a Thermo Scientific© ARGUS VI mass spectrometer has been established in China University of Geosciences (Wuhan). We designed and developed a mini efficient preparation system (80 mL), a CO2laser for heating samples, a crusher for extracting fluid inclusions within K-poor minerals and an air reservoir (31 L) and pipette (0.1 mL) system. The ARGUS VI mass spectrometer is operated by the Qtegra Noble Gas software, which can control the peripheral accessories, such as pneumatic valves, CO2laser and crusher through a PeriCon (peripheral controller). The experimental procedures of atmospheric argon analyses,40Ar/39Ar dating by laser stepwise heating and by progressive crushing in vacuo, can be fully automatically performed. The weighted mean of atmospheric40Ar/36Ar ratios is 302.22±0.03 (1σ, MSWD=0.74,n=200), indicating that air reservoir and pipette system and the whole instrument system are very stable. This laboratory is a successful pioneer example in China to establish a new noble gas laboratory with self-made peripheral accessories expect for the mass spectrometer.
