Delta Ray Connect

Research without Boundaries

The Thermo Scientific™ Delta Ray Connect™ IRIS with URI Connect represents a new and exciting 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. It allows easy interfacing with samples available in amounts as little as 80 μg of CO2, such as headspace of vials in an autosampler or an aliquot introduced through the multi-function injection port.

Precise, Verifiable Isotope Ratio Measurements
The Delta Ray Connect Isotope Ratio Infrared Spectrometer comes with a universal reference interface (URI) that provides fully automated referencing and calibration for verifiable measurements and long term confidence. Smart referencing adjusts the reference gas concentration to the sample to achieve superior performance. With the optional dilution box, samples with CO2 concentration from 200ppm to 100% can be analyzed.

Utilizing state of the art mid-infrared spectroscopy, the simultaneous determination of δ13C and δ18O empowers scientists to make profound scientific discoveries in a wide variety of research fields requiring analysis of discrete samples such as water/aquifer research, paleoclimate research and microbiology.
