The Delta Ray Road Trip


Attributing the source of CO2 presents challenges for environmental agencies and research institutions. CO2 isotope ratios carry information about the emitter. However, their continuous monitoring presents a complex task. The Thermo Scientific Delta Ray CO2 Isotope Ratio Infrared Spectrometer (IRIS) enables scientists to perform isotope ratio analysis directly where the sample is taken. On a road trip through Canada, the analyzer was installed in an RV and continuously monitored the CO2 concentrations, 13C and 18O isotope ratios coast to coast.
