The analysis of metals using inductively coupled plasma–mass spectrometry (ICP-MS), ICP-atomic emission spectroscopy (ICP-AES), and atomic absorption can serve many purposes in environmental, health, and forensic studies. Yi He, a chemistry professor at John Jay College of Criminal Justice at The City University of New York, has been using these elemental analysis techniques for fingerprinting and provenance of counterfeit cigarettes and as an educational tool. Here, she discusses some of that work. In a recent paper (1), you discuss a method for the investigation of lead and cadmium in counterfeit cigarettes using microwave digestion followed by ICP-MS analysis. What benefits does this method offer compared to others? ” alt=”” />The analysis of metals using inductively coupled plasma–mass spectrometry (ICP-MS), ICP-atomic emission spectroscopy (ICP-AES), and atomic absorption can serve many purposes in environmental, health, and forensic studies.

Highlights

  • FTIR and XRF are useful analytical techniques for tobacco identification.
  • Elemental profiles highlight Ca, Cl, K and Fe as indicators of tobacco provenance.
  • FTIR identifies a highly discriminative tobacco spectral fingerprint region.
