LIBS Technique for Identification of Crude Oils

摘要

LIBS technique for the identification of trace elements in oil samples from different sources using a compact LIBS system was used. In order to address the difficulties presented by the characteristics of the samples, two pretreatment stages, freezing and thermal treatment by ultrasound were performed. Obtained results are described and compared in both cases. It is demonstrated the potential of the technique to identify the origin of oil is by its composition.
