Chemical Ionization Mass Spectrometer
The Chemical Ionization Mass Spectrometer was developed by NOAA. This instrument can take high-precision measurements of gases such as nitric acid, water vapor, and hydrochloric acid. This instrument was designed to take measurements accurately in the boundary layer. The detection limit for CIMS is in the parts-per-trillion range, and the temporal resolution is 50s.
