File name : 'cap.m'. This file can be used
for calculating the migration time of a certain ion
in capillary electrophoresis
Four input values : 'Ld','Lt','mu_e','V' and 't_eof'
One ouput value : 't_m'

Ld = length capillary till detector (m)
Lt = total length of capillary (m)
mu_e = effective ion mobility (m^2*V^-1*s^-1)
V = electric potential (V)
t_eof = migration time of the electroosmotic flow (s)
t_m = migration time of the ion

Input syntax : cap(Ld,Lt,mu_e,V,t_eof)

NOTE 1: The effective ion mobility is equal to
the apparent ion mobility subtracted from the ion
mobility of the electroosmotic flow
(mu_e = mu_a - mu_eof)

NOTE 2: For positive ions mu_e > 0
For negative ions mu_e < 0
For neutrals mu_e = 0
