NexaFlo® for Seawater Testing

Reliable, Automated Analysis of Low-Level Nutrients in Marine Samples

Seawater is a high-salinity matrix dominated by major ions at millimolarlevels, while nutrient concentrations vary from elevated in coastal watersto sub-µmol/L or sub-ppb in open-ocean and deep-sea samples. Ultra-tracemeasurement therefore requires equipment with stable baselines, precisereagent handling and robust control of flow and reaction conditions toensure reliable results across this wide concentration range.

NexaFlo® Excels in Low-Level Seawater Nutrient Analysis. NexaFlo® is engineered to meet these requirements, applying proven Grasshoff chemistries for nitrate, nitrite, phosphate and silicate, and the OPA fluorometric method for trace ammonium.
