In chromatography, no real plates are used, although the strategy of a theoretical plate, as a distinct area where just one equilibrium is preserved, remains. In a selected liquid chromatographic separation, the quantity of theoretical plates and the peak equivalent to a theoretical plate (HETP) are associated simply by the duration of your column
