Leah MindorffGeological Survey of Canada - QuebecWe aim to develop a low-cost method to extract low concentrations of methane (CH4) from permafrost samples in order to measure δ13C and δD values and prepare for Δ13CH3D and 12CH2D2 measurements. This method will involve concentrating, purifying, and storing the CH4 present in the samples. As clumped isotopic measurements are anticipated, a challenge will be keeping the CH4 molecules intact. Current purification ...
