Head space(HS)solid-phasemicro extraction(SPME)combinedwith gaschromatography–mass spectrometry (GC–MS) was used to analyze the volatile fraction of ambers of different geological origin. In particular, Romanian (romanite)and Baltic (succinite)amber samples were studied.Both types of amber have nearly similar bulk chemical compositions and could probably reflect only some differences of paleo biological and/or diagenetic origin. The present study shows that amber headspace fingerprint, obtained bySPME/GC–MS, can provide a simple and quasi non-destructive method capable of romanite/succinite differentiation. Among the numerous compounds present in the headspace,a number of few informative variables could be selected that were able to differentiate the ambers as demonstrated by Principal Component and Cluster Analysis.

Abstract
Head space(HS)solid-phasemicro extraction(SPME)combinedwith gaschromatography–mass spectrometry (GC–MS) was used to analyze the volatile fraction of ambers of different geological origin. In particular, Romanian (romanite)and Baltic (succinite)amber samples were studied.Both types of amber have nearly similar bulk chemical compositions and could probably reflect only some differences of paleo biological and/or diagenetic origin. The present study shows that amber headspace fingerprint, obtained bySPME/GC–MS, can provide a simple and quasi non-destructive method capable of romanite/succinite differentiation. Among the numerous compounds present in the headspace,a number of few informative variables could be selected that were able to differentiate the ambers as demonstrated by Principal Component and Cluster Analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
