Figure 2. The electropherograms of real samples treated with different percent of acetone. Condition: The CE procedure was performed on fused silica capillary (41 cm × 75 μm I.D.) at 17 kV using a pH3.1 60mmol/L phosphate buffer as run buffer and detecting at 200 nm. Real samples were treated with different ratio of acetone as were shown in Figure 2.
