CIT-CIMS
California Insitute of Technology Chemical Ionization Mass Spectrometer
The CIT Chemical Ionization Mass Spectrometer (CIT-CIMS) is an in situ airborne single-mass spectrometer operated by the California Institute of Technology (CIT). It uses CF3O-ion chemistry along with compact time-of-flight and triple quadrupole spectrometers to measure specific atmospheric trace gases, including nitric acid, hydrogen peroxide, and sulfur dioxide. It was designed with rapid-scan capabilities, enabling operation at high temporal resolution (10 Hz) and detection over a wide mass range. CIT-CIMS is primarily used for airborne observations but can also be employed for ground-based measurements.
