ALS Scandinavia offers thorium isotope ratio analysis of ²³⁰Th and ²³²Th. Analysis of thorium isotope ratios is useful in a variety of fields including:

• Biochemistry
• Dating

The analysis of thorium (Th) isotopes can be carried out by two techniques, ICP-SFMS (high resolution ICP-MS) and MC-ICP-SFMS (multicollector ICP-SFMS). ALS Scandinavia has developed a matrix separation method that can be applied on prior to analysis for significantly improved measurement uncertainty.

Research - thorium 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 publication relating to thorium isotope analysis:

• Existence of long-lived isomeric states in naturally-occurring neutron-deficient Th isotopes
