A new portable system that performs simultaneous particle induced x‐ray emission and x‐ray fluorescence analysis is described. It is based on the use of a 244 Cm radioactive source as α‐particle and x‐ray emitter, coupled to a Si drift detector. Particular care has been devoted to the choice of the materials surrounding the source. X‐ray fluorescence spectra are presented, showing high detection efficiency for elements from Na (K lines) to Pb (L and M lines). The system can be used as a qualitative tool for ‘fingerprint’ analysis and, in some cases, as a quantitative one. Examples are presented and discussed. Copyright © 2007 John Wiley & Sons, Ltd.
