Research

In addition to providing routine measurements, ALS Scandinavia also conducts research on isotopes in close co-operation with several external institutions, particularly the Divisions of Applied Geology and Chemistry at Luleå University of Technology. This has resulted in a number of publications in the scientific literature. For more information, see the list below.

Our laboratory holds two multi-collector (MC) ICP-MS systems: one Neptune and one Neptune Plus. By using MC-ICP-SFMS, ALS Scandinavia can offer several high-precision isotope ratio measurement packages (see analytical packages) based on methods developed during the course of this collaborative research.
