Part of the former UVM cosmogenic extraction laboratory



Processing samples for cosmogenic nuclides is a tedious and time consuming process. The overall goal of the process is to extract and purify microgram quantities of Al and Be from 20-40 grams of pure quartz. To get to this point we do numerous procedures which we illustrate and explain for you below!
