Research conducted at the ALS laboratory in Luleå, Sweden has to date resulted in over 100 scientific publications and more than 3000 citations. The latest article covers analysis of ultra-trace level elements by ICP-SFMS in samples characterized by complex composition of the matrix.

This article is now available for a limited period of time on elsevier.com. The performance of double focusing, sector field mass spectrometry (ICP-SFMS) for determination of ultra-trace elements, including technology critical elements (TCE) in environmental and clinical matrices was critically evaluated. Various instrumental configurations and sample preparations, pre-concentration and matrix separation methods were tested and compared.
