The 20-22 is the dedicated continuous flow isotope ratio mass spectrometer for hyphenated stable isotope analysis.

Backed
by 20 years of development, the 20-22 analyser offers the highest accuracy
and precision for stable isotope analysis.
An extensive range of automated
sample preparation units gives the researcher the flexibility to measure 15N, 13C, 18O and 34S in a host of applications.
It is the only analyser that has been purposely designed to measure 2H
by continuous flow methodology.
The novel 120° ion optics came out of a design study to find the best geometry for both dual-inlet and continuous flow use and to improve sensitivity for new applications. True stigmatic focusing results in high sensitivity. Novel ion optical design results in an instrument having high dispersion with a short ion path length. This gives exceptionally high stability and has the distinct advantage of low abundance sensitivity when being used for continuous-flow. The high dispersion hydrogen spur gives complete separation of HD from He without the need for shields or voltage driven retardation grids.
