Electrophoretic3
The retention time of a solute should then be within the range: t M ≤ t r ≤ t c {\displaystyle t_{M}\leq t_{r}\leq t_{c}} Charged analytes have a more complex interaction in the capillary because they exhibit electrophoretic mobility, engage in electrostatic interactions with the micelle, and participate in hydrophobic partitioning. (wikipedia.org)
A sample solution is injected from the inlet end of the capillary, electric field is applied to the capillary ends, and components migrate to the detector point with different velocities due to distinctions in their electrophoretic properties. (lumexinstruments.es)
