Airsense High Speed Multi-component Gas Analyzer - 58717 Principle of Operation

Targeting the specific needs within the wide range of appli-cations, the series AIRSENSE is based on the measurementprinciple called Ion Molecule Reaction (IMR). By using the IMR technique, the measurement becomesfast, selective and free of any interference. Unlike oth- ers, no fragmentation or overlapping spectra can dam- age the interpretation of the detected results.IMR means using primary ions with lower energy level(10 eV .. 14 eV) to completely ionize the probe gasmolecules. The signal/noise ratio will be optimized bythe integrated octopole separator, focusing the primaryions and filtering out any interferences. The quadrupolemass filter (0-500 amu) then separates the moleculesfor further detection at the fast pulse counter. The temperature and pressure compensated sample gasinlet guarantees the correct measurement and avoidsany discrimination of the gas.Any contamination due to condensation or particulatematters is minimized.
