The table shows the data obtained for the separation of the components Methyl acetate (A), methyl propionate (B), and methyl n-butyrate (C) in a 1.1 m capillary column. Time of retention of the non-retained species, in this case air, is 0.3 min. Calculate the number of plates for each compound and explain why it is possible to have different values in the number of plates for each compound if it is the same column.
