Microwave-induced combustion (MIC) was feasible for nuclear FG quality control.
- class="label">•
LODs obtained by MIC and determination by atomic spectrometric techniques were satisfactory for quantification of all elements.

MIC absorbing solutions of 4 mol L- 1 HNO3 (for Ag, As, Cd, Ga, Hg, In, Pb, and Zn) and inversed aqua regia (for Bi, Sb and Sn) were required for quantitative recovery of all elements.
