Prompt gamma-ray activation analysis (PGAA) is typically used for the determination of elemental composition and concentration of solid samples (ca. down to ppm range). Liquids and gaseous samples can also be measured.
The PGAA method is based on the neutron capture in nuclei of the sample material and the subsequent detection of prompt gamma-rays emitted during deexcitation of the compound nuclei:
PGAA is a non-destructive tool for the analysis of major and minor components, especially advantageous for the assay of light elements (unique for H and B) and certain trace elements (Cd, Hf, rare earths). In the strong neutron beam at FRM II, however, neutron activation can also be performed, and thus many more trace elements can be detected (elements in the 4 – 6 period).
