ANU in Canberra revisited.
As our focus on our Laser Ablation IRMS collaboration with Terra Analitic and Teledyne Photon Machines continues, we thought we would revisit an LA-IRMS installation from early 2024.
Professor Stewart Fallon from world-leading Australian National University’s Research School of Earth Sciences has been involved with Sercon equipment for quite a few years, working on N & C samples on an HS2022 and GSL (a combustion EA which is also linked to a needle injection autosampler which can be used for Gas, Solid and Liquid – basically the same as the current Sercon IsoEArth or IsoEArth+)
Stewart has added a stand-alone HT-EA furnace to his system so he can now look at 18O using pyrolysis which Sercon’s service engineer Dave Harris linked to the existing 2022.
As well as this, Stewart acquired a CryoFlex to go with the laser he built for the ablation of samples, which Dave also installed. The main method for this at the moment is for 13C in organic samples such as tree rings.
One of his PhD students, Oliver Medd, also pictured, also uses the expanded set up for ablation of tree rings in investigation of the growth rings within a local native tree species, commonly known as snow gum. Snow gum is Australia’s highest elevation tree species, and can potentially aid in deciphering previous climatic conditions and dieback events.
