Figure 2: The effect of pH*s on the separation of the reaction mixture. Buffer: Imidazole 15 mM, CTAB 35 mM in methanol/acetonitrile 65/35 (v/v). pH* (adjusted with H3PO3): (a) 6.01, (b) 6.50, and (c) 7.02. Voltage: 20 kV. Detection wavelength: 214 nm. Injection: 5 kV/5 sec. Capillary: 50 μm I.D., 40.0 cm total 29 cm effective.
