The Atmospheric Pressure Ionization Mass Spectrometer (APIMS) is an in situ spectrometer manufactured by Process Insights. It has been deployed on aircraft, research vessels, and field sites to collect measurements of ultra-high purity gases such as oxygen, hydrogen, carbon dioxide, carbon monoxide, methane, water vapor, and nitrogen. It uses Atmospheric Pressure Ionization (API) techniques and mass spectroscopy to detect gas concentrations. APIMS has an analysis time of around 1 second per component and has a detection limit of less than 5 ppt depending on the gas being measured.
