General Purpose Benchtop Atmospheric Inlet Mass Spectrometer

Benchtop atmospheric inlet gas analysis system with precision triple filter mass spectrometer and closed ion source. Heated vacuum chamber and oil free pumping system ensures highest accuracy for low level organic species analysis. Application specific options for optimised operation where gas streams contain significant amounts of light gases. Ideal for TGA coupling, fermentation, environmental gas analysis, catalysis etc

MKS Cirrus benchtop atmospheric inlet mass spectrometers are compact gas analysers that deliver rapid,accurate and quantitative measurement for a wide range of processes including general thermal analysis, TGA MS, catalysis, fuel cell, and environmental studies. The heated inert silica capillary inlet and precision triple quadrupole analyser ensure unrivalled stability and sensitivity over a wide dynamic range from ppb to percent levels. Specific configurations are available for optimised measurement of processes with He carrier gas, corrosive gases, processes with variation in upstream pressure and with a wide range of standard interfaces for connection to commercial TGA equipment.
