摘要：We report a chemical assessment of the explosive chamber in the projector system used during the sampling operation of the Hayabusa2 project at the surface of the C-type asteroid Ryugu.Although the explosion process was designed as a closed system, volatile combustion gases and semivolatile organics were produced together with quenched carbonaceous product.The chemical compositions of the gases, organics, and inorganics were investigated in the screening analysis.A solid-phase microextraction technique and thermal desorption coupled with gas chromatography/mass spectrometry analysis revealed that aliphatic (
