First PLE/LC-HRMS (Orbitrap) method to determine high-intensity sweeteners in fish samples. Different clean-up strategies were evaluated to reduce the high matrix effect. In-cell clean-up with alumina and on-cell clean-up with hexane were selected. The method was validated in different fish species according to their lipid content.
