Inductively coupled plasma mass spectrometry (ICP-MS)

Agilent 7700x ICP-MS

Agilent 7700x ICP-MS

Instrument: Agilent 7700x ICP-MS

How it works

  1. An inductively coupled plasma (ICP) is used to atomise and ionise the sample.
  2. A mass spectrometer is used to separate and detect ions by their mass-to-charge (M/Z) ratio.

The detector can achieve linear performance from parts per trillion or lower, up to hundreds of parts per million in solution. The excellent sensitivity of the instrument and the very efficient collision / reaction cell interface means that analysis of 'difficult' elements such as V, Cr, As can be particularly good.

Applications

This technique is routinely used to analyse trace and ultra-trace levels of most metals and some non-metals in:

  • digests of rocks, minerals and organic materials
  • digests of man-made materials
  • waters
Elements routinely determined by ICP-MS: 

Li, Be, Al, Sc, Ti, V, Cr, Co, Ni, Cu, Zn, Ga, As, Rb, Y, Zr, Nb, Mo, platinum group elements, Cd, Sn, Sb, Cs, Ba, rare earth elements, Hf, Ta, W, Re, Tl, Pb, Th, U
