Characterization of multiple prompt gamma-ray analysis (MPGA) system at JAEA for elemental analysis of geological and cosmochemical samples

► Offline sorting modes of the coincidence data in MPGA were evaluated for elemental analyses. ► MPGA detection limits for some studied elements were improved around one order of magnitude than those obtained by other PGA facilities. ► For some elements, which cannot be determined by conventional PGA, it was observed that they could be determined by MPGA. ► Analysis of the hydrogenous meteorite Orgueil by MPGA implies that it can be used for elemental analysis with sufficient accuracy.
