DIC‑d13C in seawater
Apollo acidification system coupled to a Picarro G2201-i analyzerDissolved Inorganic Carbon - δ13C |
Methodology
Four ml of sample is transferred to a cooled chamber where phosphoric acid is added for transformation of dissolved inorganic carbon to CO2 gas, which is then sparged and sent to the Picarro analyzer for analysis of carbon isotopic composition (d13C) as well as quantitative determination of dissolved inorganic carbon (DIC (uM.l-1)).
