Thermo Scientific Delta Ray Isotope Ratio Infrared Spectrometer (IRIS) with URI Connect

Scientists can now benefit from a portable infrared spectrometer designed to provide continuous measurement of isotope ratios and CO₂ concentrations in air and in containers. The Thermo Scientific Delta Ray Isotope Ratio Infrared Spectrometer (IRIS) with URI Connect extends the continuous measurement of isotope ratios and concentrations of CO₂ in air to discrete samples, such as headspace analysis or direct injection of small amounts of CO₂.

The instrument was designed with field portability and operational simplicity in mind so that scientists can place it right at the point of the research interest. By simultaneously detecting 13C and 18O, the system allows scientists to measure both isotopolgues and concentration in one step, without destroying the sample.

The URI Connect system lets the user interface with samples containing as little as 80 µg of CO₂, such as in vials, syringes or bags, which can then be analysed with the Delta Ray IRIS analyser. The interface balances the concentration of reference gases against that of the sample, targeting accuracy with minimum effort from the user.
