Dissolved Inorganic Nutrients

ODF chemistry laboratory offers colorimetric determination of the following dissolved inorganic nutrients:  NO3 + NO2, PO4, SiO4, NO2 and NH4.  ~25 mL are necessary for shore based analysis.  Preservation should be by freezing samples in 30 mL centrifuge tubes upright at < 0°C.

Nutrient analyses are performed on a SEAL Analytical  segmented continuous-flow AutoAnalyzer 3 (AA3). After each run strip charts are reviewed for any problems and final concentrations (micromoles per liter) are calculated using SEAL Analytical AACE software. The analytical methods used are described here.
