Definition | The Sunburst SuperCO2 system is a CO2 measurement system designed for measuring CO2 gas mole fractions in liquids on board ships or in the laboratory. The instrument outputs the mole fraction of H2O in the equilibrated gas and the mole fraction of CO2 in the air equilibrated with the water sample. It operates on the principle of equilibrating a gas stream to match the partial pressure of the dissolved CO2 in a liquid stream. It uses a low volume gas stream equilibrated via a showerhead or contactor (membrane) type equilibrator. The system does not dry the sample, and takes ambient readings periodically and runs standard gas series. The instrument contains a power supply, power board, DAQ, air pumps, multiport valve, and restriction valves. The system can be used with different non-dispersive infrared (NDIR) gas analysers, either the LI-COR LI-840A or LI-COR LI-850. CO2 measurements are from an undried sample and can range between 0 and 20,000 ppm with a 1.5 % accuracy. H2O measurements can range between 0 and 60 mmol/mol with an accuracy < 1.5 %. | ||
