The cationic analyte of Problem 34-14 was separated by capillary zone electrophoresis in a 50-cm capillary at 20 kV. Under the separation conditions, the electroosmotic flow rate was 0.65 mm s21 toward the cathode. If the detector were placed 40 cm from the injection end of the capillary, how long does it take in minutes for the analyte cation to reach the detector after the field is applied?

A certain inorganic cation has a electrophoretic mobility of 5.13 × 10-4 cm2 s-1 V-1. This same ion has a diffusion coefficient of 9.1 × 10-6 cm2 s-1. If this ion is separated by capillary zone electrophoresis with a 50-cm capillary, what is the expected plate count, N, at applied voltages of
