Jean-François HélieUQAM - Geotopδ13C values are expressed relative to VPDB defined by the calcite standard NBS19 in the 1980s. To improve interlaboratory consistency a second anchor (lithium carbonate, LSVEC) was introduced in 2006 which is now known to be isotopically unstable. With the new reference materials made available by IAEA in 2020, it is now possible to realize the VPDB independently from LSVEC. It has recently been shown that using NBS19 & LSVEC or ...

Paul MiddlesteadOttawa UniversityThe physical properties of helium are unique and make it more and more attractive for multiple emerging applications from high end electronics to super magnets found in MRIs.  Helium is always being produced  thru alpha decay and extracted with natural gas.  However processing plants have limited capacities and the US reserve is now closed, conjuncture has created the 4th world crisis and the short term future is unce...

Daniele L. Pinti, Samuel Bolduc, Crystal Brochard, Lucille Daver, Hugo Raymond, Marion SabyUQAM-GeotopNoble gas laboratory at Geotop is able to analyze stable isotopes of noble gases He, Ne, Ar, Kr and Xe in fluids, fluid inclusions and rocks. The laboratory is actually working onto geothermal resources, groundwater dating, diamonds fluid inclusions, cosmogenic 3He dating. In this presentation we present the techniques are used in this "are" and "noble" discipline for analyzi...

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 ...
