Abstract
► A method is proposed for the determination of Cu in insulating oils by GFAAS. ► The method was optimized using a multivariate strategy using the Doehlert design. ► The model presented good predictive capacity. ► Hexane was the best solvent for the preparation of stable solutions of the oils. ► Trace concentrations of Cu could be determined in new and used insulating oils.
