Delta V™ Isotope Ratio Mass Spectrometer

Need the flexibility to perform all isotope ratio mass spectrometry (IRMS) applications in a single analyzer?  Thermo Scientific™ Delta V™ IRMS systems combine outstanding sensitivity with excellent linearity and stability to tackle applications as diverse as δ13C analysis of PAHs in soil, 15N/14N monitoring in chlorophyll derivatives, and detection of honey adulterants. Delta V systems can be equipped with a wide range of sample preparation devices and inlets, including preconcentrators, elemental analyzers, GC interfaces, LC interfaces, and continuous flow inlets, to ensure your instrument system is perfectly suited to your application.

Outstanding sensitivity

  • Sensitivities up to 800 molecules per CO2 ion in dual-inlet mode and 1100 molecules per ion in continuous-flow mode
  • Fiber optic signal transmission eliminates ground loops and other sources of electronic noise

Versatility to tackle almost any application

  • Up to 10 collectors in a wide range of configurations, supporting all isotope ratio MS applications in the mass range up to m/z 96
  • Simultaneous mass range up to ±25%
  • Available preconcentrators, elemental analyzers, GC interfaces, LC interfaces, and continuous flow inlets
  • On-line H2 capability
  • Upgrade path from Delta V Advantage system to Delta V Plus system

Highly robust and reliable design

  • Monolithic analyzer with fixed alignment of all ion optical components, including the
  • electromagnet, ensures unprecedented reliability and robustness.
  • Integrated signal amplifiers and digitizers eliminate connections for greater reliability
  • Fixed-position ion optics require no alignment during installation or maintenance
  • Optimized pumping strategy enables single-stage turbo pumping for all normal continuous-flow applications
  • Comprehensive, automated diagnostics are provided for analyzing performance

Compact and user-friendly design

  • Small footprint requires less lab space
  • Space for on-line peripheral on top
  • Dual inlet, μ-molume and multiport are inside, out of the way
  • Continuous flow interfaces can be controlled from the front panel
  • All pumps are located internally for less clutter and noise

Choice of instruments

  • Delta V Advantage IRMS is capable of all standard applications, including H2 analysis under helium carrier gas load
  • Delta V Plus IRMS delivers additional functionality for a wider scope of applications. There is full upgradeability from the Delta V Advantage system to the Delta V Plus system if analytical demands increase


DELTA V - One Concept - Two Isotope Ratio Engines
The DELTA V Advantage and DELTA V Plus share the revolutionary ion optical and functional design of the DELTA V platform ...

DELTA V Advantage
The DELTA V Advantage exceeds the performance of the DELTAplus XP in virtually all aspects. Its sensitivity for CO2 in Dual Inlet mode is better than 1200 molecules per ion. The standard collector configuration is the Universal Triple Collector. H2 collectors with on-line hydrogen capability are optional. The DELTA V Advantage delivers high performance in Dual Inlet and Continuous Flow mode. Excellent linearity is guaranteed with or without helium carrier gas flow. If the analytical needs of the laboratory change, the DELTA V Advantage is prepared for a field upgrade to the DELTA V Plus.

The DELTA V Plus is the highest performance DELTA ever. Its sensitivity is second only to the MAT 253, recognized as the top-of-the line Isotope Ratio MS. The ion optics have been refined, resulting in the highest possible ion transmission. This leads to a sensitivity of 800 molecules per CO2 ion in the Dual Inlet mode and, more importantly, 1100 molecules per ion in the Continuous Flow mode, which is the preferred operating condition for all continuous flow applications.
The DELTA V Plus can accommodate up to 10 collectors, ensuring flexibility to cover all isotope ratio MS applications in the mass range up to m/z 96. Its versatility puts virtually no instrumental limit to your research.
... and all the proven Isotope Ratio MS technology available only from Thermo Fisher Scientific.
