The C and N isotopies of different plants, algae or phytoplankton differ significantly. The isotopy of the same plant at different sites can also differ significantly. The C and N isotopy in organic material in sediments and soils can be used, for example, to reconstruct the origin and composition of plant material at that site.

We analyse C and N isotopy (δ13C, δ15N) in dried plant material or in pulverised soils and sediments after expulsion of the carbonate carbon fraction.

We are happy to advise you to determine the appropriate analysis for your problem.
