Comparative chromatograms obtained by analysis of the bottled sprite samples. Experimental conditions: mobile phase (ACN/H2O = 95/5, v/v), flow rate = 0.8 mL/min, nm, and injection volume = 20 μL. Peak orders: 1: DMP, 2: DBP, and 3: DOP; Symbols: a: original sprite sample without pretreatment, b: spited sample through NIP cartridge after spiting with DMP, DBP, and DOP at 0.3, 0.3, and 0.3 mg/L, respectively, c: sprite sample through MIP cartridge after spiting with DMP, DBP, and DOP at 0.3, 0.3, and 0.3 mg/L, respectively. d: standard solution, e: spited sample through PLS cartridge after spiting with DMP, DBP, and DOP at 0.3, 0.3, and 0.3 mg/L, respectively.
