## Description
NOC requires a total alkalinity (TA) and dissolved inorganic carbon (DIC) analytical system for the high-quality analysis of seawater samples in support of ongoing carbon observing and climate-monitoring activities. MARIANDA is the exclusive manufacturer and supplier of the only commercially available system capable of analysing both TA and DIC from the same sample within a single instrument. This combined approach reduces sampling uncertainty, minimises water demand during research cruises, and delivers significant efficiencies in laboratory and shipboard space.
