Theoretical plates definition
WebbResolution is an important HPLC performance indicator usually assessed by how quickly and how completely target components in a sample separate as they pass through a column. Resolution is measured by dividing the difference in peak retention times by the average peak width. Resolution can also be expressed in the Resolution Equation as a ... WebbThe theory assume that column is divided into number of zones (N) called theoretical plate. Definition. Method of separation in which the component to be separated are distributed between two phase; stationary phase and mobile phase which move on stationary phase in a definite direction.
