Inductively Coupled Plasma

Inductively Couples Plasma Mass Spectrometer

Inductively Coupled Plasma Mass Spectrometry (ICPMS) is a technique used for measuring multi-element concentrations from trace to major component levels. ICPMS employs argon plasma as the ionization source and uses a mass spectrometer analyzer to detect positive charged ions.

CEAR houses a VG PQExcell instrument, equipped with the following accessories:

  • Laser Ablation Microprobe for element analysis in solid samples
  • Gas kit for element analysis in organic matrices
  • Collision cell technology (CCT) for attenuation of polyatomic interference ions

Among the main applications of ICPMS include: identification and quantification of elements in chemical, environmental,biological and geological samples; speciation of metal oxidation states and ionic forms; and measurements of isotopic ratios.
