Inductively coupled plasma atomic emission spectroscopy (ICP-AES)

Thermo iCap 6500 Duo ICP-AES

Thermo iCap 6500 Duo ICP-AES

Instrument: Thermo iCap 6500 Duo

How it works

  1. An inductively coupled plasma (ICP) is used to produce excited atoms from a sample. These emit electromagnetic radiation at wavelengths characteristic of a particular element.
  2. A spectrometer separates and resolves these lines and measures their strength.

Solution volumes required for analysis: depending on the application 5-10 mL

Detection limits: from 100s parts per billion to 1 part per billion


This technique is routinely used to analyse major, minor and some trace elements in:

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

Al, As, Ba, Ca, Cd, Ce, Co, Cr, Cu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Rb, S, Sc, Si, Sr, Ti, V, Y, Zn, Zr

  • analysis of waters from sewage treatment plants
  • chemical analysis of meteorites and lunar rocks
  • investigation of the potential reuse of incinerated waste
  • quantification of silicon content in plants
  • study of elemental tracers in biological samples
  • detection of platinum-group elements in industrial samples
