The evaluation of fatty acid ratios in latent fingermarks by gas chromatography/mass spectrometry (GC/MS) analysis.

Despite advances in DNA, fingermarks remain one the best forms of evidence available. While fingermarks are routinely analyzed in terms of their patterns, it may be possible to obtain additional information in terms of their chemical composition. If successful, a chemical analysis of the constituents of a fingermark may give scientists additional information that may help in the identification of a person.
