Inductively coupled plasma atomic emission spectroscopy (ICP-AES)
The Varian Vista Pro
Instrument: Varian Vista Pro
How it works
- 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.
- A spectrometer separates and resolves these lines and measures their strength.
Solution volumes required for analysis: usually 5 mL or lower
Detection limits: range from low parts per million to low parts per billion
Applications
This technique is routinely used to analyse major, minor and some trace elements in:
- digests of rocks, minerals and organic materials
- 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
Examples:
- 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
