Delta V

The ThermoFisher Scientific Delta V Advantage is a stable Isotope Ratio MS. Samples can be introduced to the system via a Temperature Conversion Elemental Analyzer (TC/EA) with smart EA function or via a Gas Bench II setup. All peripherals are interfaced to the Delta via a Conflo IV device that automates reference gas inlet and sample dilution.

The Delta V advantage is a stable isotope ratio mass spectrometer. The Delta V IRMS is designed to perform high precision measurements of isotope ratios of H/D, ¹³C/¹²C, ¹⁵N/¹⁴N, ¹⁸O/¹⁶O, ³⁴S/³²S,³⁷Cl/³⁵Cl from a variety of materials. Prior to analysis by the mass spectrometer, the samples are transformed into pure gaseous substances: H₂, N₂, CO, CO₂ and SO₂. This is achieved by oxidation, reduction or high temperature conversion using different inlet and preparation systems for which the Delta V provides a flexible and open platform. The Delta V in the Chemical Analysis Laboratory is connected to a Flash EA 1112 HT with a smart EA function to enable auto-dilution and a GasBench II sample preparation device; these sample preparation devices are interfaced to the mass spectrometer via an intelligent interface - the Conflo IV.
