To study systems with large mass-to-charge ratios or systems that have very complicated isotope patterns, we need a spectrometer with the ability to accurately determine masses so we can be sure we are studying the right ion. For this we use a Fourier transform ion cyclotron resonance mass spectrometer(FT-ICR MS). In this technique, the mass-to-charge ratio(m/z) of an ion can be experimentally determined by measuring the frequency at which the ion processes in a magnetic field.

SCISAT-1 is the first new Canadian scientific satellite since the ISIS-II mission in 1971.... The satellite will be carrying a customized Canadian-built Fourier Transform Spectrometer(ACE-FTS) as part of the Atmospheric Chemistry Experiment(ACE) mission, which will run at least two years.(The feasibility of including a second scientific instrument, Measurements of Aerosol Extinction in the Stratosphere and Troposhere Retrieved by Occulation(MAESTRO), is being evaluated.) The ACE mission's goal is to take a variety of measurements in the Earth's stratosphere and troposhere to advance scientist's understanding of ozone depletion, particularly above Canada and the Arctic region.
