The migration level is often defined given that the velocity at which the species moves in the column. Plus the migration price (UR) is inversely proportional into the retention situations.
Peak width is some time from the start from the signal slope to reaching the baseline pursuing repetitive drops during the detector signal.
Mainly because of the force needed to push the mobile stage and sample throughout the tightly packed columns, HPLC was initially called superior-force chromatography.
