Optimisation of Pressurized Liquid Extraction for the Determination of Seven Selected Polychlorinated Biphenyls in Feed Samples
Pressurized Liquid Extraction was utilized for the extraction of seven selected polychlorinated biphenyls (28, 52, 101, 118, 153, and 180) from a naturally contaminated fishmeal and two feed samples fortified with a naturally contaminated fish oil sample. In order to assure sufficient extraction efficiencies, the extraction solvent, the extraction temperature, and the flush volume were optimised b
