TOC-L with TNM-L: Simultaneous Measurement of CO₂ Fixation and Nitrogen Content in Microalgal Biomass

Introduction

Research and development on microalgae-derived feedstocks for sustainable aviation fuel (SAF) has been gaining momentum. Effectively advancing this research requires the rapid and quantitative assessment of microalgal CO₂ fixation capacity and nitrogen dynamics, both of which are closely linked to biomass productivity and lipid accumulation and underpin the evaluation of environmental contribution and the optimization of production processes. This Application Note introduces examples of measuring CO₂ fixation and nitrogen content in microalgal biomass using the TOC-L Total Organic Carbon Analyzer equipped with the TNM-L Total Nitrogen Unit.
