Measurement of TOC and TN in Marine Water Algae Culture Solution

Introduction

The culturing of microalgae in various types of non- edible biomass has been receiving considerable attention in recent years. In particular, microalgae that inhabit seawater are favored due to the low cost of the culture solution and the wide choice of culture locations. Various nutrients, such as nitrogen compounds, are added to these types of microalgae cultures. However, nutrient concentrations must be managed within an appropriate range depending on the type of microalgae and the culture conditions. The Shimadzu TOC-L Series Combustion Type Total Organic Carbon Analyzer can directly measure the total organic carbon (TOC) and total nitrogen (TN) content in high-salt samples such as seawater, without requiring dilution of the samples. Here, we introduce an example of simultaneous measurement of TOC and TN in seawater using the TOC and TN measurement system consisting of the TOC-L_CPH total organic carbon analyzer for microalgal biomass measurement and the TNM-L unit for total nitrogen (TN) measurement.
