Separations were performed in a 16 μm i.d. capillary with etched capillary outlet lengths of 175, 88 and 55 μm. EC detection was performed using a 30 μm diameter carbon fiber microelectrode with a flame-etched 10 μm diameter tip. Detector volumes, peak efficiencies, and peak areas are calculated as reported as in Table 1. Sample concentrations and buffer conditions as in Figure 2.
