The present work is focused on the optimization of an analytical method in order to obtain a suitable separation of three pesticides used in museum collections in order to prevent pest attack. A major inconvenient is their high toxicity that can affect museum`s staff health. In this paper, the pesticide analysis was optimized by varying 7 methods, 2 GC columns (ZB-5MSi and DB-35MS) and 2 solvents (ethyl acetate and hexane). The most satisfactory results were obtained when ZB-5MSi column and ethyl acetate were used. Future studies will continue with the extraction optimization and the validation of the final procedure. © 2020, Politechnica University of Bucharest. All rights reserved.
