Analysis of Microalgae Biomass by TOC and TG

Introduction

Microalgae have various attractive features, as they can be used to produce oil without competing with food production. In comparison with other biofuels, productivity per unit time and area is higher and there are many choices of cultivation site. Microalgae display different growth behaviors depending on cultivation conditions, and it is considered necessary to understand the changes in their organic carbon and inorganic carbon contents. A total organic carbon (TOC) analyzer can be used for the analysis of these carbon components. Moreover, direct analysis of microalgae in the wet state is possible if a solid sample combustion unit is used, and the carbon content in the dried microalgae can also be evaluated easily by using the combustion unit in combination with thermogravimetry (TG) analysis. This article introduces analysis results of three species of microalgae.
