Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

NexION 2000 PerkinElmer

Model: NexION 2000 PerkinElmer

Location: 017 Brauer Hall

Description: ICP-MS is a type of mass spectrometry that uses an inductively coupled plasma to ionize the sample. It atomizes the sample and creates atomic and small polyatomic ions, which then detected. It is a method for determining trace elements and isotopes using a mass spectrometry in a wide-variety of environmental and biological samples because of its low detection limits (parts-per-trillions level), high sensitivity, wide linear dynamic range, and ability to measure about 80% of the periodic table. ICP-MS is ideal for analyzing samples with low regulatory limits. The analysis involves testing a liquid samples by nebulizing a portion of the solution into an argon plasma.  Solid samples first digested using an appropriate acid solution to prepare for this analysis.  It is a powerful quantitative technique. 


  • Extended Dynamic Range capabilities provide the ability to detect high and low level      elements in a single sample run.
  • Simultaneous analysis of multiple elements.
  • Two gas channels (Helium and Ammonia) combined with two modes of operation offer better interference removal, delivering better detection limits/ improved data accuracy.
  • Extremely powerful technique for rapid elemental chemical analysis and isotope ratio measurement. 
  • EPA Method 200.8: Determination of trace elements in waters and wastes. 
  • QC/QA protocols for standard procedures.

Typical uses:

  • Practically every discipline where inorganic analytical support is required. This includes environmental, geological, biological, medical, nuclear, metallurgical (semiconductor industry), final products and nutritional studies.
  • How mineral surfaces influence trace metal accessibility in aqueous environment
  • Determination of trace elements in blood and serum.
  • The analysis of drinking and natural water.
  • Monitoring the uptake of inorganic nanoparticle concentrations in biological samples.
  • Analysis of inorganic material in battery constituent.
