Almost any solid material is in principle possible to analyse by LA-ICP-MS, but some materials like certain sulfide minerals (e.g. galena, sphalerite), bones, teeth, paints and plastics, soft tissues and hair are not analysed routinely at the facility.
We specialize in the analysis of inorganic, naturally occuring materials as well as synthetic products, e.g.:
- gem stones
- Biological materials (like otoliths, shells, horns, or fish scales)
- Synthetic materials like glasses and pressed powder pellets
- Archeological samples (e.g. rock axes, ceramics)
Analysis of almost any solid material is in principle possible to perform by LA-ICP-MS, but the following materials are not routinely performed at GEUS: metals including sulfide minerals, bones, teeth, paints and plastics, soft tissues and hair.
NB: Major element composition is typically used as internal standard for concentration determinations. Thus, to quantify data the concentration of at least one major element constituent (e.g. Si, Ca or Mg) that is to be used as internal standard must be known prior to laser analysis. Typically, this is obtained by electron probe micro-analysis (EPMA), XRF or akin technique.
