The solvent ratio difference between present row and next row increases or decreases as a exponential
curve. In general, the gradient elution is used for separation of duplicated peaks. YL9111 Binary pump
has a exponential curve program, but use gradient elution by linear curve when it operates with YLClarity
software.
