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.
