TOC and TN Measurements of Seawater
30 Jan 2019For pollution control of the ocean and in the research of the ocean environment, the measurement of total organic carbon (TOC) is regarded as an important index of organic contaminants contained in seawater. At the same time, the measurement of total nitrogen (TN), which is known to cause eutrophication, is also attracting attention for environmental pollution control and in ecological research. Seawater has an NaCl content of approx. 3.5 %.
