The application of inductively coupled plasma mass spectrometry (ICP MS) in the determination of the concentrations of trace elements in steel wires was investigated for the forensic discrimination of wires with diŠerent origins; the discrimination is carried out by comparing elemental compositions. Approximately 5 mg of a chip taken from the wire was accurately weighed and dissolved in a mixture of 100 ml HCl and 100 ml HNO 3 by heating at 80°C for 30 min. Following the addition of 100 ml of 5 mg/ml Y as an internal standard and 200 ml of 7M HCl, the matrix iron in the solution was removed by extraction with 200 ml MIBK. This extraction was repeated twice, and 300 ml of the aqueous phase was heated at 150°C for 1 h after the addition of 250 ml H 2 SO 4 . This solution was diluted to 25 ml by 1 HNO 3 , and then the solution was used to determine the concentrations of Cr, Mn, Ni and Cu by ICP MS. The measured values of these elements in NIST 16f (Steel Basic Open-Hearth) showed satisfactory good agreement with the certiˆed values with RSDs from 1.0 to 2.1. A comparison of the concentrations of the four elements determined by using the present method can be carried out to diŠerentiate among the 21 possible pairs that can be formed from 7 wires produced by diŠerent manufacturers.
