Proton Induced Gamma-ray Emission (PIGE)

Proton Induced Gamma-ray Emission (PIGE) analysis is based on the detection of the prompt gamma rays emitted from nuclei that are in an excited state following a charged particle induced nuclear reaction. The energy of the gamma ray is indicative of the isotope present and the intensity of the gamma ray is a measure of the concentration of the isotope in the sample. PIGE is a rapid, nondestructive technique that, in principle, could be used in the analysis for any element. In practice, we utilize PIGE in the analysis of light elements lithium, boron, and fluorine which are often difficult to determine by other analytical techniques. Because the technique is based upon specific nuclear reactions, the sensitivity of PIGE varies greatly from isotope to isotope. In addition, the sample matrix will also influence the the detection limit of an element because of variations in the background of the gamma ray spectrum.
