Portable isotope ratio infrared spectrometer

The Thermo Scientific Delta Ray is a portable isotope ratio infrared spectrometer for on-site isotopic analysis. Its URI Connect interface extends the continuous measurement of isotope ratios and concentrations of CO₂ in air to discrete samples, such as head space analysis or direct injection of small amounts of CO₂. By simultaneously detecting ¹³C and ¹⁸O, it can measure both isotopologues and concentration in one step without destroying the sample. The URI Connect system handles samples containing as a little as 80 µg of CO₂.
