12:10pm - 12:30pmAn online preparation system for carbonate analysis at elevated temperatures

Isotopic analysis of carbonates plays a pivotal role in various scientific fields, particularly in the study of paleoclimatology, geochemistry, and environmental science. Carbonates are valuable proxies in isotopic studies due to their widespread occurrence and their ability to record environmental conditions at the time of formation. The isotopic composition of carbon and oxygen in carbonates is utilized to infer past climatic conditions, diagenetic processes, and carbon cycling. Specifically, δ^13C values provide insights into carbon sources and sinks, while δ^18O values are indicators of paleotemperatures and palaeoceanographic changes. The incorporation of dual clumped isotope (Δ47 & Δ48) analysis has furthered our understanding of carbonate systems. Clumped isotope analysis involves measuring the abundance of ^13C-^18O bonds within CO₂ molecules released from carbonates, offering a temperature proxy independent of the water’s isotopic composition. This method enhances the reconstruction of past temperatures and offers greater accuracy in paleoclimate studies. This presentation introduces a new preparation system developed by Nu Instruments to convert carbonate containing sample material to CO2 through acid digestion. The system has been developed to improve the digestion of impure carbonate materials such as dolomite, aragonites and magnesites. The preparation system enables routine analysis of these sample types within shortened time frames compared to conventional methods utilizing elevated temperatures and a stirring mechanism for each sample.
