Bipolar Chemical Ionisation Mass Spectrometer for trace gas analysis on an aircraft

The Centre for Atmospheric Science requires a fast switching bipolar chemical ionisation mass spectrometer to facilitate trace gas analysis on the British Atmospheric Research Aircraft (ARA) operated by the Faculty for Airborne Atmospheric Measurements (FAAM). To allow a wide range of measurements, this instrument must facilitate the operation of multiple reagent ions (up to 6 simultaneously) that can be flexibly interchanged on the aircraft and provide complete measurement cycles at time resolution sufficient to a...
