The sample is loaded onto the column, as well as nonpolar parts interact additional strongly Using the nonpolar stationary phase, resulting in their separation with the polar components.
The migration level could be outlined given that the velocity at which the species moves from the column. As well as the migration fee (UR) is inversely proportional to your retention instances.
