Paint analysis does not include :

  • A.Sequence of layers
  • B.Minerological profile
  • C.Pyrolysis gas chromatography
  • D.Trace elemental composition

Answer: B

Paint analysis does not include a mineralogical profile.

Forensic paint examination compares a questioned chip with a known sample by its sequence of layers (colour, number and thickness, seen under the microscope), by the organic binder, often identified by pyrolysis gas chromatography or infrared spectroscopy, and by its pigments and fillers through trace elemental composition (for example by SEM-EDX or XRF).

A mineralogical profile, the identification of the mineral grains present, is a method of soil and geological examination, not part of the standard scheme for paint.
