For the initial analysis of the sample returned from space, it must be highly essential that the sample is not physically destroyed. Using three nuclear analytical methods, namely instrumental neutron activation analysis (INAA), instrumental photon activation analysis (IPAA) and neutron-induced prompt gamma-ray analysis (PGA), we could non-destructively determine a total of 37 elements including most major and minor elements. Based on elemental abundances obtained, we have tentatively assigned two unknown samples, 1G and 2G as metal-missing L chondrite and CV chondrite, respectively. Thus, this study clearly demonstrates that the analytical scheme once proposed for the first phase of the competition can best work for the initial chemical analysis of the sample returned by the MUSES-C space mission.
