This paper describes a reserved-phase HPLC method for detecting clenbuterol (CB) and
ractopamine (RP) using an isocratic solvent-free mobile phase. The separations were performed
a Kaseisorb LC C1-300-5 (100 4.6 mm, 5 mm) with 0.05 mol/L octane sulfonic acid
mobile phase and a photodiode array detector. The total run time was
