We are requesting funding for vacuum pumps for thermal ionisation mass spectrometer housed at the GEOTOP UQAM-McGill Research center at the Université du Québec à Montréal. These pumps will replace aging and now obsolete pumps for our most heavily used mass spectrometer. The pumps are  required to lower the pressure of the sample chamber from atmospheric levels to analytical levels of 10(-7) Torr. The present pumps require more frequent maitenance and the manufacturer has advised us they can no longer supply the necessary parts for continued maintenance. A replacement of the pumps is crucial for continuing our research programs. The mass spectrometer in question supplies the bulk of geochronological and tracer isotope data for studies ranging from the evolution of the Earth to climate change.

我们正在申请资助位于蒙特利尔魁北克大学GEOTOP UQAM-McGill研究中心的热电离质谱仪真空泵。这些泵将取代我们最常用的质谱仪的老化和过时的泵。需要泵将样品室的压力从大气水平降低到10（-7）Torr的分析水平。目前的泵需要更频繁的维护，制造商已通知我们，他们不能再提供必要的零件，以继续维护。更换泵对于继续我们的研究计划至关重要。这台质谱仪为从地球演化到气候变化的研究提供了大量的地质年代学和示踪同位素数据。
