Ultra high-performance liquid chromatography (uhplc) uses sub 2.0 μm diameter particles and pressures up to 100 mpa to achieve increased resolution or decrease the run time while maintaining adequate resolution. when run on a 50.0-mm-long × 3.0-mm-diameter phenyl uhplc column, a compound has a retention time of 0.560 min and a width at half height of 2.02 s. calculate the number of theoretical plates, n, and the plate height, h, for this column under the given conditions.
