Dissolved Inorganic and Organic Nutrient Facility

Dissolved inorganic nutrients (Total Nitrate, Nitrite, Phosphate and Silicate) are analysed using a QuAAtro39 segmented flow auto-analyser from Seal Analytical (Figure 1). Micromolar Ammonium measurements are also available on request instead of Silicate measurements using the salicylate colorimetric method.

Dissolved Organic Carbon (DOC) and Total Dissolved Nitrogen (TDN) in seawater and freshwater samples are analysed with a TOC-VCPN with ASI-V auto sampler and TNM-1 unit from Shimadzu (Figure 2).
