title: Trace element determination in serum by proton-induced x-ray emission.
abstract: We report the use of proton-induced x-ray emission (PIXE) as an analytical method in clinical research. The experimental set-up and target preparation procedures are briefly discussed together with the methods of automatic data acquisition and analysis. Results from a clinical project involving rheumatoid patients receiving chrysotherapy are presented.
