Delta Ray CO2 isotope ratio isotope spectrometer 

This is an infrared laser-based spectrometer that measures δ13C and δ18O in CO2 and CO2 concentration. The instrument is set up with a universal reference inlet and an autosampler that allows measurement of CO2 from discrete samples such as CO2 derived from dissolved inorganic carbon in water samples or carbonates as well as direct measurements of CO2 in air. 

The system is able to provide high precision measurements in the laboratory and in the field, for example when deployed on a ship for isotope results in near real time during scientific expeditions.
