位于弗莱贝格的阿尔贡实验室配备了一台小体积(∼500厘米)Argus惰性气体质谱仪，该仪器连接到一条低体积(<；500厘米)气体提取管线，该管线包括一台二氧化碳热激光器和一个带自动进样器的电阻炉，用于阶梯加热实验。无需包裹即可将样品转移到熔炉中，从而最大限度地减少空白信号。气体净化由两个SAE AP10N吸气剂泵(ST101)执行，一个在室温下保持，另一个在∼400C下保持。该实验室用于广泛的应用，从年轻的火山喷发到应用于大陆构造的热年代学研究。
The Argonlab in Freiberg is equipped with a low volume (∼500 cm) ARGUS noble gas mass spectrometer connected to a low volume (<500 cm) gas extraction line comprising a CO2-thermal laser and a resistance furnace with autosampler for step heating experiments. Sample transfer into the furnace is achieved without wrapping to minimize blank signals. Gas purification is performed by two SAES AP10N getter pumps (St101), one hold at room temperature and one at∼400 C. The lab is used for a broad range of applications from dating young volcanic eruptions to thermochronologic studies applied to continental tectonics.
