About the UVM Cosmogenic Lab

The University of Vermont cosmogenic lab and research group are dedicated to high quality, high volume processing of samples for 10-Be and 26-Al analysis (and sometimes, but rarely, 36-Cl). Our energy is focussed on solving geologic and geomorphic problems with a sufficient number of samples to understand the intrinsic variability of natural systems. We are dedicated to training students at the graduate level while developing and freely disseminating sample processing methods.

The UVM Cosmogenic Nuclide Extraction Laboratory was first established in Perkins Hall during the fall of 1993 and the spring of 1994. The lab has occupied several different facilities in the years since. The original Perkins lab was reconstructed with support from the UVM Provost and operated from 1996 until 2004 with three fully exhausting laminar flow hoods. We relied on aged facilities to do mineral separation and quartz purification.

In 2004, the Geology Department relocated to Delehanty Hall on the UVM Trinity Campus. At that time, the cosmogenic lab moved to its new location on the third floor of Delehanty Hall with four fully exhausting laminar flow hoods, an acid recapture system and all the centrifuges and Teflon wear necessary to separate microgram quantities of Be and Al from 20-60 g of purified quartz. Issues with mechanical systems slowed our work for several years, ending with external boron contamination of the lab (from building roofing job) followed by an electrical fire that destroyed the facility. The lab has now been rebuilt with a new design and entirely new mechanical systems and furnishings. Work went well and quickly as you can see from these photos. All lab gear is brand new. As of October 2009, we are fully back on line processing meteoric and in situ 10Be. There are web pages where you can see and learn more about our laboratory facilities.

In order to make isotopic measurements, we work extensively with collaborators at Lawrence Livermore (CAMS) National Laboratory and at Purdue University (PRIME). Since its inception in late 1993, the UVM lab has served nearly 20 graduate students and a post doc working on several dozen different projects. We have processed over 3500 samples and prepared nearly 4500 targets for analysis. You can see a list of our publications and download them.
