Nutrients

Bigelow Laboratory offers high-precision nutrient analyses for aqueous and solid samples. We support clients from academia, industry, community organizations, municipalities, and government agencies, with capabilities tailored to both high-nutrient (eutrophic) and low-nutrient (oligotrophic) environments.

Our services include dissolved and particulate forms of inorganic and organic carbon, nitrogen, and phosphorus, all delivered with exceptional sensitivity and accuracy. As an oceanographic institution, we specialize in accurate determinations of ultra-low concentration or low-mass open-ocean samples, but we routinely run diverse sample types.

Contact us for details on analytical approach, sample handling, and analysis cost.

Available matrices include aqueous (marine water, brackish water, freshwater, groundwater, media, effluents, etc.) and solid (particulates on filter, sediments, animal and plant tissue, etc.).
