Analysis of foreign bodies

We have many years’ experience identifying all types of foreign bodies (fillings, teeth, dental posts, stones, metallic materials (nails, tacks etc…), insects, plastics, bones, wood) and much more.

For example: Identifying a foreign body as a fingernail

After performic acid and hydrochloric acid decomposition in a microwave, the foreign body is analysed using HPLC on a reverse phase with precolumn derivatisation and fluoroescence detection.

Analysis procedures

  • Microscopy
  • X-ray fluorescence
  • IPC-MS
  • GC-MS
  • HPLC
