Market Profile: RBS.

In Rutherford backscattering spectrometry (RBS), energetic ions are directed at a sample and the energy spectrum from the backscatter of ions is measured. It is used to determine the chemical composition and depth of elements in samples ranging from pure metals to optical coatings.

Among the advantages of RBS is that it is non-destructive, fast, matrix independent and can be used to analyze non-conducting organic and inorganic solids and powders. Applications include: measurement of the thickness of films, coatings and surface layers; surface and intersurface contaminant detection; measurement of the elemental composition of complex materials; and process control monitoring.

RBS is a specialized surface science analysis technique that is not available commercially. Academic laboratories commonly use the technique, but build their own systems. Former manufacturers of the instrument include Charles Evans & Association. RBS is often found in laboratories that use secondary ion mass spectrometry (SIMS) and Auger electron spectrometry.
