The Nordsim-laboratory is located in the Laboratory for Isotope Geology at the Swedish Museum of Natural History in Stockholm. Nordsim is a Nordic facility, funded jointly by Sweden, Norway, Finland and Denmark.
It is based around a Cameca 1280 ion microprobe, an advanced mass spectrometer which allows direct in situ measurement of isotopic and elemental composition in selected micrometer sized areas of a sample. This microanalytical capability opens new exciting possibilities in several fields of geological research.
The instrument has applications to a wide range of geological problems, from U-Pb and O isotopes in zircons to light stable isotope analysis of lunar and meteoritic samples.
