APIMS
Atmospheric Pressure Ionization Mass Spectrometer

The Atmospheric Pressure Ionization Mass Spectrometer (APIMS) is an in situ spectrometer manufactured by Process Insights. It has been used on aircraft, research ships, and field sites to measure ultra-high purity gases such as oxygen, hydrogen, carbon dioxide, carbon monoxide, methane, water vapor, and nitrogen. It employs Atmospheric Pressure Ionization (API) techniques and mass spectrometry to identify gas levels. APIMS provides results in about 1 second for each component and can detect less than 5 ppt, depending on the gas.
