Bench Top Atmospheric Inlet Mass Spectrometer for Fuel Cells

For applications where accurate discrimination of varying CO/N₂ species is particularly important. The Cirrus-NDIR extends the functionality of the base Cirrus model with the addition of a fully integrated non-dispersive infra-red CO analyser. The Cirrus-NDIR is the instrument of choice for the most demanding fuel cell, catalysis and combustion applications.

MKS Cirrus-NDIR bench top gas analysers deliver rapid, accurate and quantitative
measurement for processes where there is a requirement to monitor gas mixtures
containing varying CO and nitrogen levels, such as fuel cell and catalysis studies.
The standard Cirrus is equipped with a fully integrated nondispersive infrared CO sensor which is
both tolerant of the typical gas mixtures found in these applications, and is also responsive on
the same time scale as the mass spectrometer. The heated inlet and triple filter quadrupole
analyser ensure unrivalled stability and sensitivity over a wide dynamic range.

Cirrus-NDIR Technology:

Integrated nondispersive IR CO analyser
Full control from within Process Eye Software
Heated analyser chamber
