The determination of 37 metals in oils is performed by neutron activation analysis (NAA). The technique offer advantages for the determination of trace elements owing to the high sensitivity which become available at high thermal neutron fluxes. Fair agreement is obtained between the range for the most common metals determined by NAA and the literature values. Ultratrace levels for rare earth and other metals were estimated; some high values may be present as a result of technological contaminations.

Abstract
The determination of 37 metals in oils is performed by neutron activation analysis (NAA). The technique offer advantages for the determination of trace elements owing to the high sensitivity which become available at high thermal neutron fluxes. Fair agreement is obtained between the range for the most common metals determined by NAA and the literature values. Ultratrace levels for rare earth and other metals were estimated; some high values may be present as a result of technological contaminations.File in questo prodotto:
