Precise, Verifiable Isotope Ratio Measurements

The Delta Ray Isotope Ratio Infrared Spectrometer analyzer 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.

Isotope Ratios To-Go

The modular design, low weight and built-in referencing make the Delta Ray Isotope Ratio Infrared Spectrometer the analyzer of choice for demanding field applications such as greenhouse gas monitoring, ecology, plant science, carbon sequestration and storage research, or volcanic monitoring. No need to fill vials and wait for the analysis back in the laboratory. Instead feature rich data is acquired autonomously 24 hours a day, 7 days a week, with a time resolution as low as one second directly where the sample originates. A quickstart guide gets you going in no time.

Customer's Feedback

"A step forward in the surveillance of volcanoes is now possible. Laser spectroscopy for stable isotope analysis in the field opens new and exciting perspectives for the scientific community, such as the opportunity to perform real-time measurements of elemental and isotope composition of CO2 in volcanic gases." Andrea Rizzo Istituto Nazionale di Geofisica e Vulcanologia, (INGV), Sezione di Palermo, Italy
