2.1 Migration time

In capillary electrophoresis, during an analysis, the detector signal is recorded as a function of time to obtain an electrophoregram, like the one shown in figure 5 . This makes it possible to determine the exit time at the peak, noted t _m for migration time, of each analyte. This is equal to the ratio of the distance covered, which is the effective length $\mathcal{l}$ of the capillary, i.e. the distance...
