Axial-View ICP Optical Emission

The principle is exactly the same as radial ICP-OES, except that in axial-view ICP-OES, the plasma is viewed horizontally (end-on). The benefit is that more photons are seen by the detector and as a result, detection limits can be as much as 2-10 times lower, depending on the design of the instrument. The disadvantage is that more severe matrix interferences are observed with an axial ICP. Sample requirements are the same as for radial ICP-OES.

Yttrium was found to be effective for signal compensation in the detection of boron and titanium in human blood using axial-view ICP optical emission spectrometry (Garavaglia et al. 2002).
