ALS Scandinavia offers stable isotope analysis of a large number of isotopic systems such as 

Analysis of heavy stable isotopes can be carried out by two techniques, traditionally by MC-ICP-SFMS (multicollector ICP-SFMS) but also by ICP-SFMS (high resolution ICP-MS). ALS Scandinavia has developed numerous matrix separation methods that can be applied prior to testing of stable isotope ratios resulting significantly improved measurement uncertainty.

About stable isotopes

While unstable isotopes spontaneously disintegrate to form other isotopes over time, stable isotopes do not decay. The relative abundance of such isotopes is therefore tested resulting in isotope ratios that can be used for a variety of fields including environmental forensics (pollution source tracing), geochemistry, provenance studies and more.

Research - Stable isotope analysis

Our isotope research is done in close co-operation with several external institutions, particularly the Divisions of Applied Geology and Chemistry at Luleå University of Technology. Our research has resulted in the below publications relating to stable isotope analyses:

  • Performance of high resolution MC-ICP-MC for Fe isotope ratio measurements in sedimentary geological materials
  • Isotopic variations of Zn in biological materials
  • An inter-laboratory comparison of Si isotope reference materials
  • Isotopic analysis of the metabolically relevant transition metals Cu, Fe and Zn in human blood from vegetarians and omnivores using multi-collector ICP-mass spectrometry
  • And more...
