Abstract(#br)This work presents a strategy based on the in‐line coupling of SPE and CE for the chiral determination of cathinones ( R,S ‐mephedrone, R,S ‐4‐methylephedrine, and R,S ‐ methylenedioxypyrovalerone) in urine samples, using a sample pretreatment based on liquid‐liquid extraction. The chir...
