Analysis Equipment for ZMT's Marine Carbonate System

Supply of analysis equipment for measuring and determining at least 3 out of 4 parameters of the marine carbonate system: pCO2 analyzer with equilibrator in underway mode; TIC analyzer for liquid samples with a precision of less than +/- 2 µmol/kg at an average concentration of 2,000 µmol C/kg; pH analyzer; alternatively, titrator for Total Alkalinity with a precision of less than +/- 2 µmol/kg at an average concentration of approx. 2,200 µmol C/kg. The equipment will be used in the ZMT chemistry laboratory, on ship-based expeditions, and on expeditions to tropical partner countries for the determination of inorganic carbon and other carbonate system-relevant parameters, in compliance with the standards of the Global Climate Observing Systems (GCOS) and Global Ocean Observation System (GOOS). The detailed description is included in the tender documents.
