Inductively coupled plasma mass spectrometry (LA-ICP-MS)


Inductively coupled plasma mass spectrometry has been accessible since 2013 in our laboratory (Agilent 8800 ICP-MS triplequad). The method is useful for the determination almost all of the chemical elements and isotopes (exept hydrogen, noble gases and fluorine) in ngL-1 – mgL-1 concentration range.

Placing a collision/reaction cell between two quadrupol unit was an effective design to eliminate interferences. Beside of the low level measurements, isotope ratio determinations are although available. (e.g. concentrations of Ag, As, I, Th, and U in surface and ground waters are rutine based measured with this method). Direct analysis of solid samples is available using laser ablation coupled with ICP-MS. Concentration and isotope ratio mapping, Th/U dating of zircon christals, measurement of rare earth (REE) elements in environmental samples, and analyis of platinum group elements are the major topics for this technique.
