Paper Title:
Analysis of Copper Wires Residues in Fire Investigation
  Abstract

The in-depth composition of carbon and oxygen in copper beads formed by arc and fire were studied by XPS, respectively. Corresponding to the sputtering depth, the molten product on an arc bead surface layer is with drastic decrease of carbon content and with gentle change of oxygen content which then rapid decreases. While the molten product on a fire bead surface layer is with carbon content decreasing gradually and with oxygen content increasing. As a result, the distributing of C and O and the quantitative results can be used to identify the molten product on a bead induced directly by arc and the molten product on a bead formed by fire, as complementary technique for judgments of fire cause.
