QuEChERS as alternative extraction procedure in doping analyses

open access: yesDrug Testing and Analysis, 2023
AbstractQuEChERS is a dispersive solid phase extraction commonly applied in food analysis for residues, such as pesticides or mycotoxins for more than 20 years. Due to the quick and easy sample preparation procedure, a QuEChERS method based on ammonium acetate combined with formic acid in acetonitrile was tested for the preparation of urine samples for
