Stable isotope analysis helps to understand the processes that control the carbon and nitrogen cycling in aquatic systems. The quantitative and isotopic analysis of dissolved matter (e.g. dissolved total organic carbon, total bound nitrogen, etc.) is of particular importance since this pool is a prime conduit in the cycling of nitrogen and carbon. The iso TOC cube elemental analyzer inlet presents a new high-temperature combustion method for the quantitative and isotopic analysis of dissolved total organic carbon (TOC) and dissolved total bound nitrogen (TNb). It is the only instrument capable of performing these analyses, making it an indispensable tool for ecologists, limnologists, and oceanographers.
Highlights of the iso TOC cube
Direct δ13C isotope analysis of TOC in aqueous samples
with the possibility of column preconcentration for low TOC samples
Direct δ15N isotope analysis of TNb in aqueous samples
with the only commercially available instrument capable of this kind of analysis
High sample throughput
thanks to a direct analysis method which does not require sample preparation
High system uptime
thanks to low-maintenance design
Features
Direct δ13C isotope analysis of TOC in aqueous samples
The iso TOC cube is a combustion analyzer with greater analytical robustness and less maintenance than analyzers working with wet-chemical or UV oxidation methods.
