Isotopy of solid material

Knowledge of the isotopy of various elements in solids allows conclusions to be drawn about their formation. The S isotopy in sulfides, for example, indicates whether they were formed microbially or purely inorganically. It is also possible to draw conclusions about the source of the elements. For example, from the C isotopy of organic carbon in sediments, we can identify the C source (C3 vs. C4, marine vs. terrestrial). The C and O isotopy in stalagmites can be used to reconstruct environmental and climatic conditions (dry, wet, hot, cold, etc.) of the past.

We analyze C, N and S isotopy (δ13C, δ15N, δ34S) in pulverized solid samples (rock, ore, plants) and C and O isotopy in carbonates. Depending on the question, a pre-treatment of the samples is necessary.

We will be pleased to advise you in order to determine the appropriate analysis for your problem.
