In reversed-section HPLC the purchase of elution is the opposite that in a traditional-period separation, with additional polar solutes eluting very first. Rising the polarity on the cell phase contributes to extended retention situations. Shorter retention periods demand a cell period of reduced polarity.are created by reacting the silica particle
