Fully integrated TOC and TNb analysis of estuarine and sea water samples with the Elementar iso TOC cube® 

Identifying and quantifying the processes that control the carbon and nitrogen cycling in aquatic systems is important for mitigating urban and agricultural pollution, optimizing environmental policy and understanding global nutrient cycles. The isotopic analysis of dissolved organic carbon (TOC) and total bound nitrogen (TNb) are particularly important to elucidate the different sources, track nutrient cycling processes and help contamination identification. Here, we present the δ13C performance of the Elementar iso TOC® cube for
