New Portable Infrared Spectrometer Enables Scientists to Analyse Samples in the Field?
Jun 24 2016
The Thermo Scientific Delta Ray Isotope Ratio Infrared Spectrometer (IRIS) with URI Connect enables scientists to benefit from a portable infrared spectrometer, designed to provide continuous measurement of isotope ratios and CO2 concentrations in air and in containers.
“The demand for extending measurements of isotope ratios into the field is growing. Our transportable system addresses this need and includes full referencing schemes and workflows,” said HJ Jost, Product Manager, Delta Ray IRIS, Thermo Fisher Scientific, “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. The URI Connect interface balances the concentration of reference gases against that of the sample, targeting accuracy with minimum effort from the user.”
The Delta IRIS with URI Connect is a new solution that 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, 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.
