Figure 2

Effect of the different pH on the separation. Separation conditions: running buffer, 35 mmol/L H3BO3-Na2B4O7; separate voltage, 25 kV; operating temperature, 22°C; the detection wavelength, 275 nm; injection, 0.5 psi, 4 s. Chromatogram identification: (a) 8.6; (b) 8.8; (c) 9.0; (d) 9.2. Peak identification: 1: sarafloxacin; 2: difloxacin.
