Question

We would like to separate K+ and Ca+2 in a microchannel with a square cross section of 20 um and length of 5 cm. Find the arrival difference and traveling time of each species when the micro channel is under a potential of 1000 volts. Assume that electrophoretic mobility of K+ and Ca+2 are 3.8×104 cm2/V.s and 4.1×104 cm2/V-s respectively
