The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water. salinometer salinometer generic salinometer use salinometer when the instrument type used is unclear but the data include salinity measurements showerhead equilibrator showerhead equilibrator extracts dissolved CO2 from water A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a showerhead on the top, some headspace, a lot of beads to increase the surface exchange area between water and air, a water seal device at the bottom to allow water to overflow, but prevents air exchange between inside and outside.

Gould Flag: United States of America Vessel Type: Research Vessel; Ice Breaker DOB: Dec 1997 IMO: 9137337 The RV Laurence M. Gould is an icebreaker used by researchers from the United States' National Science Foundation for research in the Southern Ocean. The vessel is named after Laurence McKinley Gould a widely recognized American scientist, who had explored both the Arctic and Antarctic. She was built in Louisiana to replace the RV Polar Duke.
