Measurement of TOC and TN in Marine Water Algae Culture Solution

The culturing of microalgae in various types of non-edible biomass has been receiving considerable attention in recent years. Various nutrients, such as nitrogen compounds, are added to these types of microalgae cultures but these must be managed within an appropriate range. This application note describes the use of Shimadzu’s TOC-L Series Combustion Type Total Organic Carbon Analyzer in the direct measurement of the total organic carbon (TOC) and total nitrogen (TN) content in high-salt samples such as seawater, without requiring dilution of the samples.
