Explosive reference materials are significant to traceability analysis, quality control and measurement of energetic materials applied in modern weapon system. In the field of engineering-oriented application, LLM-105 and FOX-7 were proved that they had a promising prospect in used extensively as insensitive high energetic ingredients in munitions. Certification of metallic impurities in LLM-105 and FOX-7 was achieved by the microwave digestion-assistant inductively coupled plasma-mass spectrometry method. The contents of metallic impurities, including Na, K, Ca, Cr, Ni, Fe, Mg, Al, Co, Cu and Zn, in several LLM-105 and FOX-7 samples were accurately detected under the optimal conditions. And the detected results suggested that recrystallization was an effective method for high-purity explosive reference materials. This study could be helpful for the development of LLM-105 and FOX-7 candidate reference materials.
